Infrared Night Vision Thermal Imager
Basically, thermal imaging night vision devices are called passive night vision devices. The passive thermal imaging night vision device uses infrared detectors, optical imaging objective lenses and optical-mechanical scanning systems (the current advanced focal plane technology omits the optical-mechanical scanning system) to receive the infrared radiation energy distribution pattern of the measured target reflected in the infrared On the photosensitive element of the detector, between the optical system and the infrared detector, there is an optical-mechanical scanning mechanism (the focal plane thermal imager does not have this mechanism) to scan the infrared thermal imager of the measured object and focus on the unit or On the spectroscopic detector, the infrared radiation energy is converted into an electrical signal by the detector, which is amplified and converted into a standard video signal to display the infrared thermal image on a TV screen or monitor. This kind of thermal imaging night vision device observes the same target in total darkness and daytime, and is not affected by light.
At the end of the last century, with the development of thermal imaging technology, due to the technical advantages of thermal imaging technology over traditional night vision devices, the US military gradually began to equip infrared night vision thermal imagers. Infrared night vision thermal imagers have been continuously developed in the past 10 years, and the cooperation between RNO and the US military has also promoted the development of infrared night vision thermal imagers in civilian applications. RNO, a well-known military enterprise in the United States, can be said to have contributed a lot.
