1. A binocular device, comprising:
- (a) an input display source for transmitting light constituting a multicolor image having a spectrum which comprises a first sub-spectrum and a second sub-spectrum being different from said first sub-spectrum; and
(b) a light-transmissive substrate formed with an input diffraction grating, a left eye output diffraction grating and a right eye output diffraction grating,said input diffraction grating being positioned and constituted to provide;
(i) for said first sub-spectrum, the left eye output diffraction grating with a view of a portion of the image other than a left peripheral portion of the image, and the right eye output diffraction grating with a view of a portion of the image other than a right peripheral portion of the image, wherein said portion of the image other than said left peripheral portion incidents on said substrate at a first range of incident angles and said portion of the image other than said right peripheral portion incidents on said substrate at a second range of incident angles, said second range of angles being different from said first range of angles; and
(ii) for said second sub-spectrum, the left eye output diffraction grating with a view of a portion of the image other than a right peripheral portion of the image, and the right eye output diffraction grating with a view of a portion of the image other than a left peripheral portion of the image, wherein said portion of the image other than said right peripheral portion incidents on said substrate at a third range of incident angles and said portion of the image other than said left peripheral portion incidents on said substrate at a fourth range of incident angles, said third range of angles being different from said fourth range of angles.

Abstract
A binocular device for transmitting an image into the eyes is provided. The binocular device comprises a first monocular device, for providing one eye with a first asymmetric field-of-view, and a second monocular device for providing another eye with a second asymmetric field-of-view, where the first and second asymmetric field-of-views are mutually complementary to a combined field-of-view, wider than each individual asymmetric field-of-view.
