China OEM Micro driving module - Infrared Thermal Imaging Shutter for Thermometer Thermal Imaging Camera Night Vision – Jinde

The thermal imaging shutter is used in a thermal camera to act as a reference for periodic detector calibrations in order to provide a more accurate image of the thermal scene the camera is capturing. It is built between the lens and the detector, and the shutter switch is manually activated by setting the time interval. The presence of the shutter is to accommodate the temperature measurement defect of the detector. Since the low-end detectors and detectors are currently subject to process level and software technology, they cannot be adaptively adjusted according to the external temperature and humidity.

Therefore, when the camera is observed for a period of time or when the observed temperature and humidity of the object changes, the detector parameters are reset by the occlusion of the shutter to achieve the purpose of temperature measurement and image calibration.
