Several development stages of low-light night vision technology

Low-light night vision technology is dedicated to exploring the acquisition, conversion, enhancement, recording and display of target image information at night and other low-light conditions. Its achievements are concentrated in the effective expansion of human vision in the time domain, space and frequency domain.

Application prospects of low-light night vision technology

Low-light night vision technology has been used in night reconnaissance, aiming, vehicle driving, photoelectric fire control and other battlefield operations, and can be combined with infrared, laser, radar and other technologies to form a complete photoelectric reconnaissance, measurement and warning system.

Common faults and maintenance methods of low-light night vision devices

The following are common faults and solutions for low-light night vision devices. If the fault is not listed below or the problem cannot be solved according to the following instructions, you can consult us and our optical engineers will give you a good solution.

How to use low-light night vision device

It is normal for the device not to turn on when the ambient illumination is high (usually more than 40LUX). The device has anti-glare protection function to protect the image intensifier from damage. Under strong light outdoors during the day or when there is light indoors, do not open the objective lens cover before turning on the power. At this time, you can view through the small hole in the center of the lens cover.

Protective measures for safe use of low-light night vision devices

In terms of design, low-light night vision devices will use physical methods or photoelectric control methods to prevent low-light image intensifiers from burning out. These are passive protection methods.

How low-light night vision devices work and the difference between green and white images

Low-light night vision device refers to the use of natural night skylight such as weak moonlight, starlight, atmospheric glow, galaxy light, etc. as illumination at night, with the help of an image intensifier (also called an image intensifier tube) to amplify and amplify the weak photons reflected back from the target. An instrument that converts into visible images to enable nighttime observation.
