  • Omnidirectional imaging optics with 360°-seamless telescopic resolution
    Patent number: 8797406
    Abstract: A multifacet mirror comprises a catoptric structure configured to reflect light from a first field of view onto an image plane comprising a plurality of sensors, the catoptric structure having a surface comprising a plurality of facets separated by a plurality of catoptric regions; wherein a facet of the plurality of the facets has a second field of view that is smaller than the predetermined field of view; and wherein a catoptric region of the plurality of catoptric regions between two facets of the plurality of facets is configured to reflect light from a world point within the first field of view onto two of the sensors of the plurality of sensors.
    Type: Grant
