Can a thermal imager really see people through walls? High Score Solve 20

No, the thermal imaging camera cannot go through walls.

In nature, any object with a temperature above absolute zero (C) radiates infrared energy (heat) outward according to its temperature, but this energy is not visible to the human eye. In general, the higher the surface temperature of an object, the more infrared energy is emitted.

The infrared thermal imager is essentially a thermal sensor, which focuses on the infrared energy emitted by the object through the optical lens, and transmits the energy to the infrared detector, and then converts the heat distribution of the detected target into an infrared thermal image that can be recognized by the human eye through photoelectric conversion, electrical signal processing, image intelligent algorithm and other technologies.

Because the infrared thermal imager relies on heat rather than light to sensing, it has many advantages that visible light does not have, such as breaking through night barriers, rain and fog, glare, haze and other harsh conditions, and can work around the clock.

However, thermal imaging does not allow through walls, because most reinforced concrete walls are very thick and block infrared radiation from the other side of the wall. Unless the contents of the wall can cause enough temperature difference to cause heat conduction, it is possible to be sensed by thermal imaging.

Does the thermal imager have a penetration function? The answer is yes.

Thermal imagers are the "eyes of the night" and are an important visual extension of human beings. The thermal imager is not affected by visible light, and can penetrate darkness, glare, haze, and smoke, and has a very wide range of application space.

However, thermal imagers cannot penetrate walls, because walls are generally thick enough to resist infrared radiation on the other side of the wall. However, if the object inside the wall can cause a sufficient temperature difference, the thermal imager can sense it. Engineers can use thermal imagers to detect problems such as water leaks without having to tear down walls to evaluate.

Similarly, thermal imagers can also be used for underfloor heating inspections to quickly identify fault points without damaging the ground.

Yes, but you can only see that the red and blue colors represent hot and cold, respectively.

Yes, it's hard to see! You can only see an approximate view of London!

With the development of science and technology, scientific and technological products are constantly enriching people's lives, and in recent years, the wide application of infrared thermal imager in the civilian field has made people have more awareness of it. There are also many clips about thermal imaging in many movies, some of which can penetrate the wall to see the situation in the house, which leads many netizens to think that thermal imaging can penetrate the wall and see the people in the house, in fact, this part of the netizens are confused by the clips in some movies, I am here to tell you very clearly, infrared thermal imagers are unable to penetrate the wall and detect the people in the house.

However, the thermal imager has a certain penetration effect, it is not affected by low illumination, strong light interference, can penetrate smoke, haze, some special materials, etc., and the bottom is the effect of penetrating plastic bags shot with Arrow E6+.

Shoot thermal imaging through the plastic bag).

Arrow E6+ thermal imager can indeed receive infrared radiation emitted by human hands in plastic bags, and the imaging effect is very clear, see here is not worried about personal privacy issues, this is not necessary, the clothes in the picture above are not penetrated, infrared thermal imaging cameras are achieved by collecting thermal radiation from different objects, unless you are wearing some special material fabric and translucent under the naked eye, the thermal imager can penetrate, but in fact, there are not as many as the naked eye. Nylon fabrics can't penetrate even thick walls.

To sum up, infrared thermal imagers can indeed see through some materials, but when encountering completely opaque objects such as walls, they cannot fully see through as seen in movies.

No.

Thermal imaging cannot penetrate walls, and walls are generally thick enough to block infrared radiation from the other side. If you point a thermal imaging camera at a wall, it will detect the heat of the wall, and the heat behind it will not be able to reach it, and if the contents of the wall can cause enough temperature differences, the camera will be able to sense the surface of the wall. Building maintenance professionals, for example, often use thermal imaging cameras to detect problems such as water leaks or missing insulation, without having to tear down walls to assess the problem.

Precautions for the use of thermal imagers.

Atmospheric attenuation results in a decrease in the amount of radiation received by the thermal imager, and the temperature measurement is low. Try to arrange the test in the dry and clean season (spring and autumn) of the atmosphere, and the relative humidity is required to not exceed 85%. Minimize the detection distance without compromising safety.

Thermal imaging is a magical technology known as infrared thermography that converts thermal radiation images into visible images, allowing people to see things they couldn't see before. The device that makes this transition is called a thermal imager, which allows us to see what it looks like in the dark of night. Let's talk about the principle of thermal imaging:

Thermal imaging technology is based on the fact that all objects generate heat. Although many objects are indistinguishable from the outside, there is still a distinction between hot and cold on them. With the help of the colors on the heat map, we can see the temperature distribution, red and pink indicate higher temperatures, and blue and green represent lower temperatures.

The kind of movie that can be seen directly with a thermal image, thermal imaging can not see through, can only detect the surface temperature of the object, not to mention that the wall can't even penetrate the glass, because the glass surface has the temperature of glass, unless you stick to the glass and then cover the glass with heat.

Yes, because the wall has no heat, the thermal imager can only see what is hot.

Yes, after all, there is no heat in the strong and there is heat in the body.

Yes, generally speaking, the temperature of the human body is higher than that of the wall.

You can't see it completely, just see the outline of things.

Thermal imaging can only see objects that are hot.

Can thermal imaging penetrate walls?

Let me tell you clearly, from the current technology, thermal imaging cannot penetrate the wall! In our lives, walls are generally thick enough and insulated enough to block infrared radiation on the other side. If you point the camera at a wall, it will detect the heat of the wall, and the heat behind the wall will be out of reach.

However, if something inside the wall causes enough temperature differences, the camera can sense it on the surface of the wall as well. For example, building maintenance professionals often use thermal imaging cameras to detect issues such as water leaks or missing insulation without having to remove walls to assess the problem.

Can thermal imaging penetrate smoke?

Thermal imaging cameras can penetrate smoke to detect heat. While soot particles in smoke are effective at blocking visible light, they cannot block infrared radiation. At present, thermal imaging cameras are widely used in the fire protection industry.

For example, the KT384 series thermal imaging cameras are designed for the extreme heat and smoke environments that firefighters encounter on the job. Sharper thermal images are displayed on bright LCDs, making it easy to traverse the line of fire and make decisions.

Can thermal imaging penetrate concrete?

The answer to this question is basically similar to whether or not you can go through a wall, but the camera may detect something inside the concrete, such as pipes or radiant heating, causing a temperature difference with the surface of the concrete, which could be the thermal imaging camera capturing it!

Can thermal imaging penetrate metal?

In the field of thermal imaging, metal can be a tricky material. Any smooth or polished metal object can reflect infrared radiation, which can cause difficulties for personnel monitoring pipes or overheated parts of machinery. But oxide metals or metals coated with matte materials are easier to measure accurately.

A thermal imaging camera may never "penetrate" a metal object, but the temperature difference caused by the material inside the metal will be reflected on the metal surface. In this way, the camera can also achieve the detection effect.

Can thermal imaging penetrate plastic?

We do a fun little experiment with an infrared camera: hold up a thin, opaque piece of plastic (like a garbage bag) in front of a warm object or person. Infrared radiation will penetrate the plastic, allowing the camera to detect the temperature behind the plastic while blocking visible light.

However, it should be noted that this technique is only suitable for very thin plastics, which block infrared radiation.

Can thermal imaging penetrate the darkness?

Of course! Thermal imaging is completely unaffected by darkness and does not require visible light to show heat.

It should be possible, not very clear.

I can see it vaguely, but I don't know very well.

It is probably impossible to invent perspective on objects that can only see heat.

Thermal imaging cannot penetrate walls.

The thermal imaging penetration function is mainly reflected in the fact that the thermal imaging camera is not affected by weather conditions, and can clearly penetrate rain, snow, haze and other adverse weather conditions.

Principle and classification.

Infrared thermal imagers have two different principles: photon detection and thermal detection. The former is mainly used for imaging by the electrical effect generated by photons on semiconductor materials, and is highly sensitive, but the temperature of the detector itself will affect it, so it needs to be cooled. The latter, which converts the heat raised by light into an electrical signal, is less sensitive than the former, but does not require refrigeration.

In addition, the thermal imager is classified according to the operating band and the photosensitive material used.

Common thermal imagers work at 3 to 5 microns or 8 to 12 microns, and commonly used photosensitive materials are lead sulfide, lead selenide, indium telluride, lead tin tellurium, mercury cadmium tellurium, doped germanium and doped silicon. Depending on the number of sensors and the mode of movement, there are mechanical scanning, gaze imaging, and so on.

Does thermal imaging have penetration? The answer is yes.

Thermal imaging is the "eye of the night", an important visual extension of human beings. Thermal imaging is not affected by visible light, and can penetrate darkness, glare, haze, and smoke, and has a very wide range of application space.

However, thermal imaging does not allow for see-through walls, because walls are generally thick enough to resist infrared radiation on the other side of the wall. However, if the objects inside the wall can cause enough temperature differences, thermal imaging can sense them. Engineers can use thermal imaging to detect problems such as water leaks, without having to tear down walls to evaluate.

In the same way, thermal imaging can also be used for underfloor heating inspections to quickly identify fault points without damaging the ground.

Under normal circumstances, it is not, the infrared thermal imager passively receives the infrared electromagnetic waves emitted by the object, and then converts the signal to finally express it in the form of an image. The penetration ability of infrared light is very poor, worse than that of visible light, so when you are behind a wall, the general thermal imager will not be able to detect the presence of people.

If it helps you, please click to adopt, thank you!

No, thermal imaging is to detect the thermal radiation on the surface of an object, and all objects above absolute zero are constantly emitting thermal radiation, and so are walls, so they cannot penetrate walls, and transparent glass cannot penetrate them.

From the working principle of the thermal imaging camera, it can be seen that the thermal imaging camera is impenetrable to the general solid wall.

No, not only the walls can't be penetrated, not even the glass can penetrate, and the glass can block the infrared.

OK. That's what that reflection imaging looks like.

Thermal imaging can't pass through walls, but it can measure floor heating pipes. The Arrow iray thermal imager, which has the highest imaging quality and clarity, can see the floor heating pipes clearly. Missing?

At a glance, it's just expensive, but then again, good things are expensive.

The thermal imaging penetration function is mainly reflected in the fact that the infrared thermal imaging camera is not affected by weather conditions, and can clearly penetrate rain, snow, haze and other adverse weather conditions.

Thermography.

Professional doctors can conduct a comprehensive and systematic analysis of the patient's general condition in combination with clinical practice, and Kenara has overcome the one-sidedness of other diagnostic techniques limited to a certain part. The application of far-infrared thermal imaging technology has been able to detect more than 100 kinds of diseases such as inflammation, tumors, stones, vascular diseases, nervous system, sub-health, etc., involving common and frequent diseases in various systems of the human body. Many imaging instruments have varying degrees of harm to the human body, while far-infrared thermography does not produce any rays and does not require the labeling of drugs.

Therefore, it will not cause any harm to the human body, will not cause any pollution to the environment, and is simple and economical. Far infrared thermal imaging technology has realized the dream of human beings to pursue green health, and people vividly call this technology "green physical examination". It is beneficial for early detection of diseases.

Compared with X-ray, B-ultrasound, CT and other imaging technologies, one of the most important advantages of far-infrared thermography detection is early warning. Although X-ray, B-ultrasound, CT and other technologies have their own characteristics, they can only be found after the formation of the disease, and before the disease changes in tissue structure and morphology, cell metabolism will be abnormal, and the human body will undergo temperature changes, and the temperature level, the shape of the temperature field, and the size of the temperature difference can reflect the location, nature and degree of the disease. Far infrared thermography detects diseases based on abnormalities in human body temperature, so it can decipher potential hidden dangers in the absence of obvious signs in the body and detect problems earlier.

Some data show that far-infrared heat maps can detect lesions half a year or even earlier than structural images, which wins valuable time for early detection and prevention of diseases. <>
