Digital night vision devices are a very popular concept in recent years. With the rapid development of digital technology, digital night vision devices have gradually entered people's field of vision. Compared with traditional low-light infrared traditional night vision devices, what is the difference between digital night vision devices and them? What is the technical principle of digital night vision devices? I believe that many people who are interested in digital night vision devices want to know very much. Here is a brief introduction for everyone.

1. The principle of digital night vision devices

Compared with traditional night vision devices, the principle of digital night vision devices is completely different. Digital night vision devices do not use image intensifiers as image intensifiers, but use low-light CCD as image intensifiers. Low-light CCD can identify very dark light and then convert it into visible digital signals, which are displayed on the LCD screen inside the night vision device.

What is the difference between digital night vision devices and digital cameras?

First of all, digital night vision devices have a built-in LCD screen, while digital cameras have an external LCD screen. Digital cameras use ordinary CCDs, while most digital night vision devices use low-light CCDs.

It is for this reason that, like the image intensifier tube of traditional night vision goggles, the low-light CCD of digital night vision goggles is a very critical component.

At present, there are many domestic brands of very cheap digital night vision goggles, which are priced at less than 1,000 yuan. These so-called digital night vision goggles are not digital night vision goggles. They are technically assembled from traditional infrared cameras of 100-200 yuan. This cheap digital night vision goggles, on the one hand, have a very short observation distance, and more importantly, they are very harmful to the eyes. According to real user feedback, this kind of domestic digital night vision goggles will cause dry eyes and tears in general people after using them for about ten minutes.

2. How to distinguish the generation of digital night vision goggles and what is the most important thing in choosing digital night vision goggles

Just like choosing traditional night vision goggles, brightness, clarity and observation distance can still be used as important indicators for choosing digital night vision goggles.

When choosing a digital night vision goggles, first look at its brightness, clarity and observation distance without turning on the infrared light. Because night vision goggles are concealed equipment, turning on the infrared light is easy to be discovered by others. Therefore, infrared lights cannot be turned on in most usage environments.

When purchasing digital night vision devices, functional indicators should also be considered. Wouldn't it be better to have a fully functional and high-definition digital night vision device?
