The principle of operation of a thermal imaging camera
The thermal imaging camera works by detecting infrared radiation emitted by objects in the field of view. It uses hybrid microbolometer and thermocouple pixel technology, which enables precise detection and measurement of the temperature of objects. The pixels of the thermocouple record temperature changes, and the microbolometer converts this data into a thermal image. Thanks to the lack of a shutter, the camera works continuously, which allows you to monitor the temperature in real time . The received thermal image can be transmitted in the form of a video stream with a maximum speed of up to 25 frames per second , which enables ongoing analysis and control of industrial processes and other applications requiring precise temperature monitoring.
