Abstract
A wide field of view night vision system includes a head attachment apparatus configured to attach to a user's head and a night vision subsystem. The night vision subsystem includes one or more digital night vision image sensors attached to the head attachment apparatus. Each sensor receives input light and produces a digital image of the input light. A processor processes the digital image(s) to produce a wide-field image. The wide-field image spans at least 60 degrees of a user's horizontal field of view. A display and eyepiece attached to the head attachment apparatus receives and displays the wide-field image. The eyepiece is positionable between the display and the user's eye to image the wide-field image into the user's eye.
