The Function of Night Vision Camera

Firstly: the visible light at night is very weak, but people can not see the infrared is very rich. Infrared night vision helps people observe, search, aim and drive vehicles at night. Although infrared was discovered very early, infrared remote sensing technology develops very slowly due to the limitation of infrared components. It was not until 1940 when Germany developed lead sulfide and several infrared transmission materials that the birth of infrared remote sensing instruments became possible. After that, Germany first developed several infrared detection instruments such as the active infrared night vision instrument. In an encounter with the British tank column, the German Leopard tank equipped with the red sight device destroyed two British firefly tanks in one fell swone. It is worth mentioning that the German army used the active infrared night vision device in this battle. So there was also an owl searchlight vehicle that used infrared light to illuminate leopard tanks in the distance.

Secondly: night vision instrument almost at the same time, the United States is also developing infrared night vision instrument, although the time of the success of the test is later than Germany, but the first to put it into actual combat application. In the summer of 1945, when U.S. troops landed and attacked Okinawa, Japanese troops hiding in a cave took advantage of the complicated terrain and came out at night. So the United States will just make a batch of infrared night instrument emergency shipped to Okinawa, equipped with infrared night vision instrument gun rack near the cave, when the Japanese took advantage of the night just climbed out of the hole, was immediately knocked down by a burst of accurate guns. The Japanese cave unknown reason, continue to rush out, and confused to send the life. Infrared night vision instrument at the beginning of the battlefield, for the elimination of Okinawa's resistance to the Japanese army played an important role.

The active infrared night vision instrument has the characteristics of clear imaging and simple production, but its fatal weakness is that the infrared light of the infrared searchlight will be detected by the enemy's infrared detection device. In the 1960s, the United States first developed a passive thermal imager, which does not emit infrared light, is not easy to be detected by the enemy, and has the ability to observe through fog, rain and so on.

From April to June 1982, the Malvinas War broke out between the United Kingdom and Argentina. At midnight on April 13, the British attacked Port Stanley, their biggest stronghold. Minefields laid by 3,000 British troops suddenly appeared in front of the Argentine lines. All British guns and artillery are equipped with infrared night vision equipment, which can clearly detect Afghan targets in the dark. The Argentine army, however, lacked night vision equipment to detect the British, and was only passively beaten. Under the accurate attack of the British firepower, the Ah army could not support, the British took the opportunity to charge. By dawn, the British had taken the main points of the Argentine line, and the Argentine army was completely under The control of British fire. At 9 p.m. on June 14, 14, 000 Argentine troops had to surrender to the British. The British won a heavily outnumbered battle ahead of infrared night vision equipment.

In the 1991 Gulf War, the U.S. army was equipped with advanced infrared night vision equipment to detect and fire at Iraqi tanks before they could. The Iraqi army only knew the enemy was in front of them from the muzzle fire of American tanks. It can be seen that infrared night vision equipment plays an important role in modern war.
