Redesign of Armored Illuminator Optical Projection Module.

摘要

Under a previous contract, number DAAG53-76-C-0005, a compact, armored searchlight was developed for the U.S. Army Night Vision Laboratory. Field testing of that searchlight by the Army revealed some design problems in the optical projection module. Under this contract, the optical projection module was redesigned incorporating an improved infrared filter mechanism, blackout mechanism, and beamspreading mechanism. Heat transfer - characteristics were also improved. Subsequent testing of this redesigned searchlight at Fort Knox, Kentucky confirmed that the design changes eliminated the previous operational deficiencies. (Author)
