In order to correct non uniformity, a mechanical control calibration plate is installed in front of the thermal imaging detector, which will be calibrated every 10 seconds to ensure more accurate measurements. This is a thermal imaging detector undergoing calibration work, which usually experiences a lag of about 1 2seconds. This is a normal phenomenon, so please don't worry. 2.
