Digital night vision device is also called digital night vision device, its English name is Digital Night Vision. Most digital night vision devices process and convert this low-intensity light into electrical signals through a highly sensitive CCD image sensor, which is then sent to a microdisplay (a microdisplay is an LCD flat-panel display where each pixel consists of one to four Controlled between transistors, this microdisplay technology offers the best resolution of all flat panel technologies rate).
The working principle of digital night vision device: darker light --> CCD (CMOS) photoreceptor --> CPU (processed by software) --> built-in display screen --> visible image. Instead of using photomultiplier tubes, digital night vision goggles digitize an image of the available light, reproduce it in software, and push it back to the level of digital night vision in the visible image.
As mentioned above about the image sensor of the digital night vision device, the CCD photosensitive sensor, as the core component of the digital night vision device, is the "heart" of the digital night vision device, and its level directly determines the level of the digital night vision device. At present, the level of CCD sensor of digital night vision device is divided into A1, A2 and A3, which correspond to the first generation digital night vision device, the second generation digital night vision device and the third generation digital night vision device.
