MD 9930 Thermal camera
Operation details
12
NOTE:
Correct focus is important in all imaging applications. It makes sure that the infrared
energy is correctly directed onto the pixels of the detector. Without the correct focus,
the thermal image can be blurry and the radiometric data will be inaccurate. Out-of-
focus infrared images are of little value. It is one of the very few image properties that
cannot be fixed in software after the fact.
Shutter
Shutter in thermal cameras is used as a reference for periodic calibration of the
sensor. When it closes, it deflects all thermal energy from the outside and so provides
the reference for a uniform zero.
Calibration status can be easily seen as blurry or sharp image. MD 9930 supports
automatic or manual calibration.
In manual, push the Power button to recalibrate. In Auto, the camera will correct itself
automatically when it needs to.
