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. An illuminator coupled to the image processor inputs light into the underlying device based on image processing performed by the image processor.

Abstract: Extracting data in pulsed light, the method includes receiving input light at an image intensifier tube. At a power supply coupled to the image intensifier tube, current to the image intensifier tube is varied to implement automatic brightness control of the intensifier tube based on intensity of the input light received at the image intensifier tube. At a signal processor coupled to the power supply, changes in voltage or current supplied by the power supply occurring as a result of changes in the intensity of the input light to the image intensifier tube are detected. Based on the changes in voltage or current supplied by the power supply, data embedded in the input light to the image intensifier tube is extracted.

Abstract: A night vision optical device includes an underlying device configured to be sensitive to light in a first spectrum, and to provide output light based on absorbing light in the first spectrum. The night vision optical device further includes a stacked device overlapping the underlying device. The stacked device includes one or more openings formed in the underlying device to form one or more transparent regions which are transparent to the light in the first spectrum to allow light in the first spectrum to pass through to the underlying device. The stacked device is sensitive to light in a second spectrum. The stacked device outputs light in the first spectrum to the underlying device as a result of absorbing light in the second spectrum. Thus, the underlying device outputs light based both on light passing through the transparent regions and on light output by the stacked device.
