Infrared imaging system shutter assembly with integrated thermister

A method comprising:

• providing a paddle in a shutter assembly connected to an infrared sensor assembly, wherein the paddle is configured to move between a closed position blocking scene-based infrared radiation from reaching a focal plane array (FPA) of the infrared sensor assembly configured to capture thermal images of a target scene, and an open position passing the scene-based infrared radiation to the FPA;
• sensing a temperature of the paddle in the open position by a thermistor embedded within the shutter assembly;
• determining the temperature of the paddle based on voltage values of the thermistor based on resistance values of the thermistor corresponding to the temperature sensed by the thermistor;
• attenuating, by a low emissive surface of the shutter assembly adjacent to, substantially parallel with, and facing the FPA, out-of-field thermal radiation while the FPA captures the scene-based thermal radiation;
• and
• wherein the shutter assembly is configured to interface with a lens assembly disposed between the shutter assembly and the target scene.
