Abstract: An optical device. The optical device includes an underlying device that is sensitive to input light, and provides output light in a first spectrum based on absorbing the input light. The optical device further includes a stacked device, formed in an active area of a single semiconductor chip, coupled in an overlapping fashion to the underlying device. The stacked device includes first and second zones. Each zone has a plurality of active elements having a particular lateral size, where the lateral size is different for each zone. Each zone also has a plurality of transparent regions formed in the stacked device which are transparent to the light in the first spectrum to allow light in the first spectrum to pass through from the underlying device. The transparent regions are configured in size and shape to cause each zone to have a particular transmission efficiency for light in the first spectrum.

Abstract: A nightvision system includes an underlying device that provides output light in a first spectrum. A transparent optical device transmits light in the first spectrum from the underlying device through the transparent optical device. The transparent optical device includes an active area of a semiconductor chip. The active area includes active elements that cause the underlying device to detect light from the underlying device and transparent regions formed in the active area which are transparent to the light in the first spectrum to allow light in the first spectrum to pass through from the underlying device to a user. An image processor processes brightness maps produced using light detected by the first plurality of active elements. A tunable filter array coupled to the image processor filters at least a portion of the input light into the underlying device the underlying device based on brightness map processing.

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 transparent overlay display is a borderless display in which the active area extends to at least one edge of the display. Data-handling circuitry is arranged within the active area, rather than being arranged along a border of the display. The data-handling circuitry may be fabricated in the active area of the display by fabricating it below opaque pixel regions that generate the display light. This borderless configuration allows partial overlap with the intensified image by eliminating opaque borders in which the data-handling circuitry is fabricated. This borderless configuration helps to minimize size, weight, and power by reducing the size of the display and eliminating the need for bulky beam splitters.

Abstract: An optical device includes an underlying device configured output light to an optical output to output an image of objects in an environment to a user. The light is output in a first spectrum. A stacked device is configured to be coupled in an overlapping fashion to an optical output of the underlying device. The stacked device is transparent, according to a first transmission efficiency, to light in the first spectrum. The stacked device includes a plurality of electro-optical circuits including: a plurality of light emitters configured to output light, and a plurality of detectors configured to detect light in the first spectrum from the underlying device that can be used to detect the objects in the image. The light emitters are configured to output light dependent on light detected by the detectors and additional information about characteristics of the objects in the environment.
