  • Patent number: 11940613
    Abstract: An apparatus and method are provided for a night vision system including a transparent overlay display that transmit direct-view light representing an intensified image and emits display light representing a display image. The overlay display includes photodetectors arranged to detect an intensity of the incoming direct-view light, and an intensity of the display light depends on the detected intensity. In some embodiments, the intensity of the display light is spatially modulated using an amplitude or envelope of the intensity that is based on the detected local intensity of the direct-view light. In some embodiments, the intensity of the display light is adjusted to correct for loss of the direct-view light. The intensity of the display light may be controlled using control circuitry that receives signals from the photodetectors, and the control circuitry may be located on the same semiconductor chip as the overlay display.

  • Patent number: 11921286
    Abstract: This disclosure describes a novel lens system having an entrance pupil at a location matching, or nearly matching, the eye's optical system entrance pupil. The described lens system is significantly thinner than a single-aperture lens with matched entrance pupil and is achieved by using an array of camera elements. Each camera element contains camera optics called “lenslets” and a sensor (e.g., an image or depth sensor), where a lenslet can include one or more lens elements (e.g., a compound lens). Individual camera elements can be arranged such that THEIR optical axes intersect at, or near, the eye's entrance pupil location. In addition, each camera element's field-of-view (FOV) corresponds to a small sector of a large FOV. The FOVs of adjacent camera elements can be non- or slightly-overlapping so that a wide-angle image can be formed by concatenation of the individual camera element images.
