Replacement device for a driver's viewer
First Claim
1. An image intensifier system for a viewing assembly comprising:
- a housing having two opposed ends;
a Generation III image intensifier tube located in one end of said housing for intensifying an image received from the viewing system;
a fiber optic element located in the other end of said housing, said fiber optic element having an input surface which receives the intensified image and transfers the image to an output surface thereof at which location the image is dimensioned for viewing by a user of the viewing system; and
an optical lens system located in said housing and positioned between said Generation III tube and said fiber optic element, said optical lens system receiving the image from said Generation III tube, inverting the image and transferring the image to the plane of said fiber optic element; and
a power supply located in said housing for powering said Generation III tube.

Abstract
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.

9. A driver'"'"'s viewer system comprising:
-
an input window for receiving an image of a distant scene; reflecting means for receiving the image from said input window along a first optical path and directing the image to a second optical path; an objective lens assembly for receiving the image from said reflecting means and inverting and focusing the image; an image intensifier tube positioned adjacent said objective lens assembly for intensifying the image received from said objective lens assembly; a relay lens assembly positioned to receive, enlarge and reinvert the intensified image from said intensifier tube and direct the image to an image plane located beyond said relay lens assembly; means for achieving field curvature reversal of the image located at the image plane and for transferring the corrected image to a plane for viewing by the user of the system; and a biocular eyepiece for viewing the corrected, intensified image. - View Dependent Claims (10, 11, 12, 13, 14)
