ABSTRACT:
A system (10) for calibrating an image detector includes a calibration platform (16) supporting a calibration element (18). The calibration element (18) may be made up of a first lens (20) and a second lens (22), each having a curved surface to appropriately alter characteristics of reference light levels (33) generated by a reference source (24). The second lens (22) may have its surface positioned differently to the focal plane array (14) than the first lens mirror (20) for enhanced calibration operation. The reference source (24) generates the reference light levels (33) over a range of temperatures to mimic the image energy generated by the scene (12). The reference source (24) may also include a reference lens element (26) that transmits reference light energy (33) generated by the reference source (24) or reflects scene base energy (34) generated by the scene (12) and allowed to pass through the first lens (20) and the second lens (22). The calibration platform (16) operates to position the first lens (20) and the second lens (22) in front of the focal plane array (14) during calibration operation and remove the first lens (20) and the second lens (22) from in front of the focal plane array (14) during normal image detection.
