Thermal imaging night vision sight is a device that uses thermal imaging technology for night aiming and observation. The following is a detailed introduction:

Principle

Based on the principle that all objects above absolute zero will radiate infrared rays, thermal imaging night vision sights capture the thermal radiation of the target object through infrared detectors, convert it into electrical signals, and then process and convert the signals to finally present a thermal imaging image on the display. According to the temperature difference between the target and the background, the user can clearly distinguish the outline and position of the target, so that effective aiming and observation can be achieved even in harsh environmental conditions such as complete darkness, smoke, and haze.

Performance indicators

Resolution: refers to the smallest detail that can be distinguished in a thermal imaging image, usually expressed in the number of pixels, such as 384×288, 640×480, etc. The higher the resolution, the clearer the image, and the more target details that can be distinguished, but the price is relatively high.

Thermal sensitivity: also known as the noise equivalent temperature difference, is an indicator of the ability of thermal imaging sights to detect small temperature differences. The higher the thermal sensitivity, the smaller the temperature change can be detected, so that the temperature difference between the target and the background can be more clearly distinguished, and the target can be found more easily in a complex environment.

Magnification: determines the size of the target image in the scope, generally between 1x and 10x. A larger magnification can make the target look larger and clearer, but it will also narrow the field of view, which is not conducive to rapid search for the target.

Field of view: refers to the horizontal and vertical angle range that the scope can observe. The larger the field of view, the wider the area that can be observed, and the more conducive it is to quickly find the target, but the edge of the image may be distorted to a certain extent.

Advantages

Not affected by light: In a completely dark environment, no external light source is required, and only the target's own thermal radiation can be used to image, and it can be used normally in low-light environments such as night, caves, and dense forests.

Penetrate smoke and haze: Thermal imaging technology is based on infrared radiation, and smoke, haze, etc. have little effect on it. The target can still be clearly observed under severe weather conditions.

Strong target recognition ability: Thermal imaging can clearly distinguish the outline and temperature distribution of the target, and can more accurately identify and locate animals hidden in the grass and woods or camouflaged targets.

Disadvantages

Expensive: Thermal imaging technology is relatively complex, and the cost of core components is high, resulting in generally high prices for thermal imaging night vision scopes, ranging from thousands to tens of thousands of yuan.

Limited battery life: Due to the need to power infrared detectors, display screens and other components, and the high power consumption, rechargeable batteries are usually used, and the battery life is generally about 2-6 hours. Long-term use requires carrying spare batteries or charging equipment.

Poor adaptability to high temperature environments: In high temperature environments, the temperature difference between the target and the background decreases, and the effect of thermal imaging will be affected, which may lead to a decrease in the recognition of the target.

Application scenarios

Military field: It can be equipped on weapons such as rifles and sniper rifles for night combat, reconnaissance, surveillance and other tasks, helping soldiers quickly find and aim at targets in the dark, and improving combat effectiveness and survivability.

Law enforcement and security: When police patrol at night, search for suspects, and monitor important places, thermal imaging night vision scopes can help them find people and objects hidden in the dark, improving the safety and efficiency of law enforcement.

Hunting activities: When hunters hunt at night or in low light, they can use thermal imaging scopes to quickly find traces of prey and increase the success rate of hunting.

Outdoor adventure and search and rescue: In outdoor adventures, it can be used to observe the surrounding environment, discover potential dangers and find rescue targets. When searching for missing persons, thermal imaging technology can quickly scan large areas, find human heat signals, and improve search and rescue efficiency.
