Abstract

Various techniques are provided to perform flat field correction (FFC) for infrared cameras. In one example, a system includes a focal plane array (FPA) of an infrared camera configured to capture thermal image data in response to infrared radiation received by the FPA via an optical path of the infrared camera. The system further includes a memory configured to store a set of supplemental FFC values. The system further includes a processor configured to determine a scale factor based at least on a temperature and/or a rate of temperature change of an internal component of the infrared camera; generate a scaled set of supplemental FFC values based on the scale factor and set of supplemental FFC values; and apply the scaled set of supplemental FFC values to the thermal image data to adjust for non-uniformities associated with at least a portion of the first optical path.
