What is the principle of driver s night vision goggles, and the principle of night vision goggles?

Here's what you know. Visiting the forum, I found that the effect of drivers is generally not good! Wish..

Night vision goggles. It is a strengthened special lens specially worn at night, its material is ordinary film coated with yellow reflective material, there is no optical polarizer, and it can be reflected by the bright color of yellow itself when the light is dark, and enhance the clarity of road conditions. Block strong light, do not block the road surface, eliminate glare, make night driving without blind spots, and increase the brightness of rainy and foggy days.

Qiqiwang is recommended to use it at night and during the day when it is cloudy and foggy, do not use it in a strong light environment, and take off your glasses to rest for half an hour when driving continuously for more than 2 hours. It is not recommended to wear it for a long time, and try not to wear it for long drives.

Hello, the principle of night vision goggles is: 1. With a special lens, the infrared rays emitted by the objects in the field of vision can be gathered. 2. The phased array on the infrared detector element can scan the converging light.

The detector element is capable of generating a very detailed temperature pattern called a thermogram. In about 1 30 seconds, the detector array acquires temperature information and makes a thermogram. This information was obtained from thousands of detection points in the field of view of the detector array.

3. The temperature spectrum generated by the detector element is converted into electrical pulses. 4. These pulses are transmitted to the signal processing unit, a circuit board with an integrated precision chip, which converts the information emitted by the detector element into data that the display can recognize. 5. The signal processing unit sends the information to the display, so as to present the colors of each noisy booth on the display, and the color intensity is determined by the precautionary intensity of infrared transmission.

An image is generated by combining the pulses from the detector element.

There are two types of night vision goggles, one is low-light night vision goggles and the other is infrared night vision goggles.

Low-light night vision goggles amplify weak light, while infrared night vision goggles convert infrared light into visible light.

There are two kinds of infrared night vision goggles, one is active, the other is passive, and the active type is that the night vision goggles emit a beam of infrared rays, which shine on the object and then reflect back, which is equivalent to a flashlight; The passive type amplifies the infrared rays emitted by the object itself into visible light.

So, in the absence of light at all, low-light night vision goggles cannot see anything. If there is no infrared source (most things that can generate heat can become infrared sources, such as creatures, vehicles, flames, etc.), passive infrared night vision goggles cannot see anything. And active infrared night vision goggles can see things in any situation.

Different night vision goggles have different applicable occasions, and low-light night vision goggles are suitable for use when there is starlight or moon bucket light in the field.

Because the night vision goggles only show monochrome, and its display is green (you can notice that Yu Hui to the display of many meters is green), so what you see is green.

What are Night Driving Glasses?

That's what it stands for for night driving glassesNight vision goggles. , eye specialty stores and e-commerce platforms are available. Night vision goggles work by diffusing light and filtering out blue light to reduce glare. Blue light is the shortest wavelength of light in the spectrum and is more likely to cause glare when it enters the eye.

Do night driving goggles work?

Night vision goggles can be selected in a range of lens colors from yellow to amber, and yellow lenses will reduce the amount of light entering the eyes, resulting in less visibility. If you wear it at night, it may affect the clarity of driving.

In addition to glare, lenses also filter out other visible light, which makes it difficult to see objects in dim or dark environments.

According to the relevant test air damage slow study, night vision goggles do not improve visibility at night, nor do they help drivers see better on the road than when they are not worn.

Ways to potentially improve the effectiveness of night driving

1. Check your eyes and vision regularly to ensure that your eyesight fits the glasses you wear best;

2. Before driving, clean the stains on the glasses, because the stains will aggravate the glare;

3. Before driving, clean the windshield in front of you to eliminate the hidden danger of glare;

4. Replace the wipers regularly;

5. Don't drive for a long time, pay attention to reasonable rest, and do some eye care appropriately;

6. When driving at night, I feel that I am not very clear and there are obstacles, so remember to go to the hospital in time to consult questions.

The special effect of the driver's glasses (driving mirrors) is to effectively remove and filter the scattered light from the beam. The light can be put into the visual image of the eye on the correct light transmission axis, so that the vision is clear and natural. Like the principle of blinds, the light is adjusted to the same direction and enters the room, which naturally makes the scenery look soft and not dazzling.

It has a unique function that prioritizes glare removal, which has a special effect on the driver, which can improve vision and increase driving pleasure.

The direct exposure of the headlights of the opposite vehicle will cause the human eye to appear similar to night blindness and cause traffic accidents, and the night driving mirror will block the harm caused by the strong light to the eyes and reduce the accident rate. It can eliminate 100% ultraviolet rays and glare, making it safer to drive at night.

In addition, due to the particularity of the driver, the glasses must also be impact-resistant and not fragile to prevent secondary damage to the eyes in sudden accidents, so the general driving mirror can not use fragile glass materials, but should use resin, nylon and other materials! The use of PC space bulletproof lenses to protect the safety of the eyes in the event of an accidental impact of the driver, is the driver's preferred driver glasses.

When choosing driver glasses, pay attention to the following aspects.

First, choose a regular channel to buy**, it is best to go to a regular store or online** to buy. Some vendors sell very cheap driver's glasses, but they are often counterfeit products, which not only have no polarization effect, but also cannot even prevent ultraviolet rays, not only can not care for the eyes, but affect the visual effect.

Second, when choosing the color of the driver's glasses, don't be too bright colors. Gray, green and brown are the best choices for drivers, and the gray driver glasses lenses absorb any color spectrum evenly, effectively avoiding visual color aberration, and can also relieve visual fatigue. In addition, the brown driver's glasses can filter out a large amount of blue light, which can improve the visual contrast and clarity, and is effective in severe air pollution (such as sandstorms) or foggy conditions.

And light blue, light pink and other driver glasses are best not to choose.

Thirdly, if the UV rays are not particularly strong, it is recommended not to wear driver's glasses. Don't wear driver's glasses on cloudy days or when the light is very mild, as the lack of light can cause visual fatigue.
