What is the working principle and applicable range of an infrared camera?


Infrared thermal imaging cameras use infrared detectors, optical imaging mirrors and optomechanical scanning systems (the current advanced focal plane technology eliminates the optomechanical scanning system) to reflect the infrared radiation energy distribution of the measured target on the photosensitive element of the infrared detector superior. Between the optical system and the infrared detector, there is an opto-mechanical scanning mechanism (the focal plane thermal imager does not have this mechanism) to scan the infrared thermal image of the measured object and focus it on the unit or the spectroscopic detector. The detector converts the infrared radiant energy into an electrical signal, which is amplified and processed, converted or a standard video signal is displayed on a TV screen or monitor to display an infrared thermal image.


Thermal Imager

Thermal imaging cameras are widely used in military and civilian applications. With the maturity of thermal imaging technology and the emergence of various low-cost thermal imaging cameras suitable for civilian use, it is playing an increasingly important role in various sectors of the national economy. In industrial production, many equipment are often used for high temperature, high pressure and high speed operation. Infrared thermal imaging cameras are used to detect and monitor these devices, not only to ensure the safe operation of the devices, but also to detect abnormal conditions and eliminate hidden dangers in time. At the same time, thermal imaging cameras can also be used for quality control and management of industrial products.
