Abstract
A wide field of view night vision system is described. The system comprises a head attachment apparatus configured to attach to a user's head and a night vision subsystem. The night vision subsystem comprises one or more 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.
Claims19
A night vision system comprising:
- a first objective lens and a first digital night vision sensor that is not an image intensifier tube, the first objective lens imaging light from an environment onto the first digital night vision sensor, the first digital night vision sensor capturing said light imaged by the first objective lens and producing a first digital image of the light captured by the first digital night vision sensor;
- a second objective lens and a second digital night vision sensor that is not an image intensifier tube, the second objective lens imaging light from the environment onto the second digital night vision sensor, the second digital night vision sensor capturing said light imaged by the second objective lens and producing a second digital image of the light captured by the second digital night vision sensor, wherein the first digital image and the second digital image are horizontally partially overlapping;
- a processor that electronically receives the first and second digital images from the digital night vision sensors that are not image intensifier tubes and stitches the digital images together to form a wide-field digital image having at least a 55 degree horizontal field of view, wherein to stitch the digital images together the processor (1) detects the horizontal overlap of the first and second digital images and (2) stitches the digital images together based on the detected overlap to form the wide-field digital image;
- and
- a display and an eyepiece, the display receiving the wide-field digital image from the processor and displaying the wide-field digital image, the eyepiece imaging the wide-field digital image into an eye of a user.
