Paper Abstract

The designed laser radar (LADAR) system utilize a Geiger focal plane array (FPA) of 16x16 resolution which limits the field of view (FOV) of the system. To overcome this, an additional scanner module consists of 4 rotational wedges was placed in front of the optical system. Naturally, the cases to analyze as a part of the stray light analysis became extremely complex and abundant. To sort out the major cases out of all possible scenarios, the stray light analysis was performed separately according to the modules. The ghost analysis was performed backward from the FPA to the front of the optics.
