Abstract
Techniques for facilitating temperature compensation are provided. In one example, an infrared imaging system includes a focal plane array configured to capture radiation from a scene and generate image data based on the radiation. The focal plane array further captures radiation from an element associated with the infrared imaging system during capture of the radiation from the scene. The infrared imaging system further includes a temperature sensor configured to determine a temperature of the focal plane array. The infrared imaging system further includes a processing circuit configured to determine a temperature associated with the element based on the temperature of the focal plane array. The processing circuit is further configured to determine a temperature associated with an object in the scene based on the infrared image data, the temperature associated with the element, and the temperature of the focal plane array. Related devices and methods are also provided.
