Replacement device for a driver's viewer

摘要

An image intensifier retrofit system for a Generation II based driver's viewer assembly, identified as AN/VVS-2. The system includes a housing which is dimensionally the same as the Generation II tube housing. Positioned at one end of the housing is a Generation III image intensifier tube and at the other end of the housing is a fiber optic element. Positioned between the tube and the fiber optic element is a relay lens assembly. The Generation III tube receives the light from a viewed scene from an objective lens assembly of the dirver's viewer. The intensified image output from the tube is received by the relay lens system which inverts and magnifies the image and transfers the image to the input surface of the fiber optic element. The fiber optic element in turn transfers the image to its output surface from which surface the image is viewed by the user of the driver's viewer through a biocular eyepiece.
