Does anyone know what the working band of a thermal imaging camera means?

In layman's terms, a thermal imaging camera is the transformation of the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the measured target can be observed, and the heating situation of the target can be studied, which provides a basis for judgment for work and research.

The thermal imaging cameras we commonly use are passive thermal imaging tests and are very safe. According to the atmospheric window, infrared rays are divided into near-infrared, short-wave infrared, medium-wave infrared, and long-wave infrared. Long-wave infrared can be observed through air, not through walls and glass, and has the advantages of all-weather imaging, non-contact temperature measurement, and smoke penetration.

The operating band refers to the wavelength range in the technical parameters of the camera, that is, what is the wavelength of infrared light received by the camera.

According to Wien's displacement law, the detection temperature corresponding to the operating band can be calculated.

But. This does not mean that wavelengths outside the operating band cannot be detected.

The basic principle of a thermal imaging camera is Planck's law of radiation.

Radiation can occur at any temperature over a wide range of wavelengths.

Because the working band is just a recommendation,,

The corresponding temperature detection in this range is "more" appropriate, nothing more.

We don't have to worry about this when we use it.

What is Infrared?

In nature, any object with a temperature greater than absolute zero (-273) can radiate infrared light, which, together with visible light, ultraviolet light, X-rays, gamma rays, cosmic rays and radio waves, constitutes a complete and continuous electromagnetic spectrum. Its wavelength is between 1000 m and is non-visible light with a longer wavelength than red light.

How thermal imaging cameras work.

3.Thermal imaging tips:

1) The thermal image reflects the distribution of infrared radiation on the surface of the object, which depends on the spatial distribution of the emissivity and temperature of the object.

2) Different manufacturers of thermal imaging cameras have different presets of color palettes, and the effect on image color processing is also different.

3) The image on the left uses a classic iron red color palette, with yellow representing the high temperature area and purple representing the low temperature area.

To put it simply, the principle of a thermal imaging camera is to use temperature imaging to convert the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured. Objects in nature that are higher than absolute zero (-273) are constantly emitting infrared rays.

The thermal imaging camera converts infrared radiation from the surface of an object into a visible image through an optical system, an infrared detector chip and an electronic processing system.

The infrared thermal imaging camera has the advantages of not being affected by visible light, 24-hour clear imaging, non-contact temperature measurement, smoke and fog, etc., and can be applied to human body temperature measurement, industrial temperature measurement, automatic driving, safety and fire protection, outdoor observation, etc.

The infrared detector and the optical imaging objective lens are used to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector, so as to obtain the infrared thermal image, which corresponds to the thermal distribution field on the surface of the object. In layman's terms, a thermal imaging camera is to transform the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured.

Infrared thermal imaging camera is a kind of infrared thermal imaging technology, through the infrared radiation detection of the object, and the signal processing, photoelectric conversion and other means, the temperature distribution of the object of the image into a visual image of the device. If you want to buy a thermal imager, you can choose the products of Arrow Optoelectronics, which is a major military infrared manufacturer.

The biggest features are non-contact temperature measurement, night vision, and stronger penetration than visible light.

Let the common people understand the role of the thermal imager in the simplest and most understandable way, and summarize it in one sentence: the eyes in the night.

WY20071209 is more comprehensive. There are not many people in this industry in China, and there are not many companies that use them, and most of them focus on power and railway rights.

and other industries. Since last year (2011), there has been national certification training in China (existing intermediate and advanced), and the manufacturers used to train and issue certificates by themselves. At present, the training and examinations are mainly organized by the Equipment Management Association, and the training teachers are mainly Fluke instructors.

If you are interested, you can provide your own information. But it is not easy to engage in this industry as an individual, mainly because it is difficult to find business channels, and at the same time, you have to buy your own instruments (mid-to-high-end thermal imagers are more than 100,000).

Infrared thermal imaging technology is a passive, non-contact detection and recognition technology, which can use the infrared radiation signature image formed by the temperature difference or radiation difference between the target and the background or between the various parts of the target to find and identify the target, and its two basic functions are temperature measurement and night vision.

Temperature measurement, which can realize non-contact long-distance temperature measurement and fault detection, has the advantages of simple and intuitive, safe and accurate, efficient and time-saving and all-weather work. Night vision, i.e. the ability to easily detect and identify targets in the absence of light, has the advantages of all-weather operation, no fear of bad weather, long range and superior stealth.

The earliest application of infrared thermal imager originated in the military field, and was widely used in power inspection, electrical equipment maintenance, industrial automation, inspection and quarantine, security monitoring, forest fire prevention, fire rescue, police law enforcement, outdoor sports and other traditional civilian fields, as well as autonomous driving, smart home, Internet of Things, artificial intelligence, consumer electronics and other emerging fields.
