ABSTRACT:
An optical device, similar to binoculars, which includes, between the objective lens and the eyepiece a miniature screen displaying an image controlled by a computer, and an optical reflex device capable of superimposing the screen image on the image seen through the objective lens. The device also includes, selectively or cumulatively, a variable light attenuator and a light amplifier for night vision. The device can be used, in conjunction with a computer, to add further information on geographic positions, friends, enemies, infrared images, etc. into the scene seen through the binoculars.
