What is an Infrared thermal imager
Infrared thermal imager uses infrared detector, optical imaging objective lens and optomechanical scanning system (advanced focal plane technology saves optomechanical scanning system) to receive the infrared radiation energy distribution pattern of the measured target and reflect it to the photosensitive element of the infrared detector. On, 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 image of the object to be measured, and focus on the unit or the spectroscopic detector. The detector converts infrared radiant energy into electrical signals, which are amplified, converted or standard video signals to display infrared thermal images through a TV screen or monitor. This thermal image corresponds to the thermal distribution field on the surface of the object; it is essentially the thermal image distribution of the infrared radiation of each part of the target object to be measured. Because the signal is very weak, compared with the visible light image, it lacks hierarchy and three-dimensional sense. Therefore, In the actual operation process, in order to more effectively judge the infrared heat distribution field of the measured target, some auxiliary measures are often used to increase the practical functions of the instrument, such as image brightness and contrast control, real standard correction, false color rendering and other techniques.
