Abstract

A binocular-like vision system for enabling an observer to view an object. The system includes an input end that receives light from the object and an optical transfer system that receives the light received from the input end and transfers the received light to an image intensifier which intensifies the received light, wherein the intensified received light is transferred to and transmitted out of an output end of the system, wherein the light transmitted out of the output end forms a field of view of the object that is greater than a 60 degree horizontal field of view.
