Patent Images
1. A fiber optic viewing device comprising:
- at least one lens for focusing a field of view in only one direction therethrough into a parallel light path,a fiber optic bundle having an input end and an output end, each of said ends occupying a plane cut perpendicular to the direction of said fiber optic bundle and polished to have a smooth surface, all of said optical fibers being substantially parallel to one another throughout their lengths,said input end of said fiber optic bundle being oriented with respect to said at least one lens such that parallel light path enters said input end of said fiber optic bundle, andsaid output end of said fiber optic bundle being oriented so as to present at a desired location an image transmitted by said fiber optic bundle from said input end, said output end being arranged for direct viewing by an observer.

Abstract
A high quality fiber optic viewing device is provided which includes a fiber optic bundle having two ends, each end being cut in a plane perpendicular to the longitudinal axes of the optical fibers and highly polished. At the input end of the device a lens system presents a wide angle view to the bundle. The output end is able to be viewed directly or by a television camera. The device is particularly suited for use in moving vehicles, security systems and inspection of dangerous or hard to reach objects.
