Patent ID: 7499216

Claim:
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.
