Explains The Principles And Related Knowledge Of Digital Night Vision
Digital night vision is a very popular concept in recent years, with the rapid development of digital technology, digital night vision gradually into people's vision. Compared with the traditional low-light infrared night vision device, what is the difference between the digital night vision device and it? What is the technical principle of digital night vision? I believe that many people who are interested in digital night vision are very interested in understanding, the following will give you a brief introduction.
one The principle of digital night vision
Compared with traditional night vision devices, the principle of digital night vision devices is completely different. Digital night vision devices do not use an image enhancement tube as an image intensifier, but use a low-illumination CCD as an image intensifier. The low-illumination CCD can recognize very dark light and then convert it into a visible digital signal that is displayed on the LCD screen inside the night vision device.
What is the difference between digital night vision and digital camera?
First of all, digital night vision devices have a built-in LCD screen, while digital cameras are an external LCD screen. Digital cameras use ordinary CCD, while digital night vision devices mostly use low-illumination CCD.
It is for this reason that, like the image enhancement tube of the traditional night vision device, the low-illumination CCD of the digital night vision device is a very key component.
At present, there are many domestic brands of very cheap digital night vision equipment, the price is less than 1000 yuan, this kind of so-called digital night vision equipment, in fact, not digital night vision equipment, its technology is assembled from the traditional 100-200 yuan infrared camera. This cheap digital night vision device, on the one hand, the observation distance is very close, and the more important aspect is that the eye damage is very large. According to real user feedback, this domestic digital night vision device generally uses about ten minutes will appear dry eyes, tears phenomenon.
two How to distinguish the algebra of digital night vision equipment and what is the most important thing to choose digital night vision equipment
As with the purchase of traditional night vision equipment, brightness and clarity and observation distance can still be used as important indicators for the purchase of digital night vision equipment.
Choose a digital night vision device, first look at the brightness and clarity, and observation distance without turning on the infrared light. Because night vision as a concealed device, turn on infrared lights, it is easy to be found by others. Therefore, most of the use of the environment, can not turn on the infrared light.
The same digital night vision when the purchase of functional indicators also need to consider, a fully functional and high-definition viewing of digital night vision is not better?
