No-Contact Infrared Forehead Thermometer Gun consists of optical system, photodetector, signal amplifier, signal processing, display output and other parts. The optical system converges the target infrared radiation energy in its field of view, and the size of the field of view is determined by the optical parts of the thermometer and their positions. No-Contact Infrared Forehead Thermometer Gun energy is focused on the photodetector and converted into a corresponding electrical signal. The infrared thermometer signal passes through the amplifier and the signal processing circuit, and is converted into the temperature value of the measured target after being corrected according to the algorithm and target emissivity of the instrument. In addition, the environmental conditions of the target and the thermometer, such as temperature, atmosphere, pollution and interference, etc., should also be considered to affect the performance index and correction methods.
