Characteristics and advantages of infrared thermal imaging night vision goggles

Imaging principles and characteristics

Passive reception of infrared radiation: Infrared thermal imaging night vision goggles do not emit energy themselves, but passively receive infrared radiation emitted by the target object itself and convert it into a visual thermal image. This feature makes it highly concealed and difficult to be detected by the enemy or target.

Imaging based on temperature difference: The image is formed based on the temperature difference or thermal radiation difference between the target and the background or the parts of the target, so objects with different temperature characteristics can be clearly displayed. Even in the dark, the contours and positions of various objects can be distinguished by temperature differences, such as easily identifying human bodies, animals, and heating mechanical equipment at night.

Environmental adaptability advantage

All-weather work: not limited by lighting conditions, whether in the dark night, in a moonless and starless environment, or under strong light during the day, it can work normally, always provide users with clear images, and perform observation tasks around the clock.

Strong penetration ability: It can effectively penetrate common atmospheric disturbances such as fog, haze, rain, snow, and some obstructions such as smoke and thin vegetation. In severe weather conditions or complex environments, it can still find targets and obtain effective image information, helping users to better understand the surrounding situation in unfavorable environments.

Common infrared thermal imaging night vision products include: VA-6100, VA-MTB-900, VA-H619-S, VA-S01-T685L3, S01-T685B75.

Target recognition advantage

Strong camouflage recognition ability: Due to the thermal radiation imaging based on the target, even if the target is camouflaged, its thermal signal characteristics are still difficult to hide. Thermal imaging night vision devices can detect targets through camouflage, which is of great significance for reconnaissance, search, and security monitoring in military operations. It can effectively identify military equipment and personnel hidden in the grass, woods or camouflaged.

Hot spot detection capability: sensitive to heat sources, able to quickly and accurately detect hot spots in the scene, such as fire points, heating fault points, etc., in fire rescue, power inspection and other work, can help staff quickly locate the problem and improve emergency response efficiency.

Other advantages

Wide observation range: Its observation range is related to the lens and detector, generally up to 10km or more. Compared with some night vision devices with limited observation range, such as laser night vision devices, infrared thermal imaging night vision devices are more suitable for large-area observation, which can provide users with a wider field of view and help to fully understand the surrounding environment and situation.

Strong anti-interference ability: The special optical design and signal processing technology are used to minimize the degree of interference of the sensor by the external environment. Even in the environment with strong electromagnetic pulses, it can still maintain good temperature measurement accuracy and stability. In addition, it has good moisture resistance and can adapt to a variety of complex and harsh environments.

Convenient use and long life: Usually designed to be relatively light, easy to carry and operate, and most infrared night vision devices are carefully designed and manufactured to withstand various environmental conditions, have a long service life, and do not need to replace equipment frequently.

Various display methods: There are rich types of image display devices, including CRT, LED array, LCD, plasma, etc. They are flexible in application, and images can be displayed directly, indirectly, or in a mixed manner. They have good adaptability to the system, the screen area can be large or small, and they can be displayed on multiple screens. Other information can also be added to the screen, such as directly displaying temperature information.
