Abstract
A night vision goggle system having an objective lens for viewing an image scene, an image intensifier tube for amplifying a received image scene, an eyepiece lens for presenting the amplified image scene produced at the output of the image intensifier tube to a user's eye, and a fiber-optic element for folding an optical path between the image intensifier tube and one of the eyepiece lens and the objective lens thereby minimizing the length and weight of the system.
