Abstract:
A method and apparatus for calculating and accounting for non-uniformity of pixels within an infrared (IR) focal plane sensor utilizing an infrared light emitting diode (IR LED) to wash out environmental infrared light is provided. The IR LED may back propagate through an optical path of an IR sensor to illuminate pixels on a focal plane array, thereby providing data by which the non-uniformity offsets may be calculated and removed for normal operation of the IR sensor.
