Description

Infrared night vision device

Technical field

The invention relates to the technical field of infrared night vision devices, in particular to the technical field of infrared night vision devices.

Background technique

Ordinary people's eyes can't feel infrared rays, so people can't see things when there is no reflected light in the dark, and any object with a temperature higher than absolute zero radiates infrared rays, including your body. Therefore, the infrared ray-detecting device is used to detect the infrared ray, and then the analog signal is subjected to image processing methods such as background noise, amplification, filtering, etc., to restore the contour of the detected object. However, the color is difficult to restore, so the infrared night vision device sees The image is rarely colored. It is the basic principle of infrared night vision.

The infrared night vision device played a very important role in the war. In the summer of 1945, the US military landed on the island of Okinawa. The Japanese troops hidden in the cave tunnel used complex terrain and came out to attack the US military at night. So the US military urgently transported a batch of infrared night illuminators that had just been manufactured to Okinawa. The guns with infrared night vision devices were placed near the caves. When the Japanese army climbed out of the hole at night, they were immediately knocked down by an accurate gun. The Japanese troops in the cave did not know why, and they continued to rush out, and they gave their lives in a confused way. When the infrared night vision device first entered the battlefield, it played an important role in eliminating the Japanese army that was recalcitrant on Okinawa. In 1982, the Malvinas War broke out between Britain and Argentina. In the middle of the night of April 13, the British attacked the Stanley Port, the largest stronghold in the army. Thunderfields of 3,000 British troops suddenly appeared in front of the Afghan defense line. All guns and artillery in the United Kingdom are equipped with infrared night vision devices, which can clearly find the targets of the army in the dark. The Afghan army lacks night vision devices, and cannot find the British army. It only has a passive beating. Under the accurate attack of the British military firepower, the Afghan army could not support it, and the British army took the opportunity to launch a charge. By dawn, the British army had occupied several major commanding heights on the Afghan defense line. The Afghan army was completely under the control of the British military. At 9 pm on June 14, 14,000 Azerbaijans had to surrender to the British. The British military's leading infrared night vision equipment won a battle of disparity. In the Gulf War of 1991, on the battlefield filled with sand and smoke, the US military equipped with advanced infrared night vision equipment, able to find the other side of the Iraqi military tanks and fired a gun. The Iraqi army only learned that the enemy was in front of the muzzle fire when the US military tanks were fired. This shows the important role of infrared night vision equipment in modern warfare.

In addition to military applications, infrared night vision devices are also very demanding in civilian applications. They can be used for mining, hunting, etc. Traditional infrared night vision devices are used in a single way and must be operated by people and infrared night vision devices. It can't be controlled and observed remotely. For areas far from the house, the labor cost is high. The market needs an infrared night vision device. It needs to be able to make infrared night vision devices have multiple ways of use, which can be compared with traditional infrared night vision.
