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 images produced using light detected by the first plurality of active elements. An autofocus mechanism coupled to the image processor focuses the input light into the underlying device based on image processing performed by the image processor.

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. To reduce the communication bandwidth with an external controller, a frame buffer is provided to locally update pixel values of the display image, at a first frame rate. Because many pixel values remain unchanged from frame to frame, an external controller may change the pixel values stored in the frame buffer as needed, reducing the amount of information that is needed from the external controller to control the display image. Additionally, to reduce the communication bandwidth the display information may be communicated from the external controller using a high-level language. Further, some of the display information may be determined using a local processor, rather than relying on the external controller for the display information.

Abstract: An apparatus and method are provided for a night vision system that integrates functions of detecting an intensified image and transmitting the intensified image superimposed with a heads-up display. The night vision system includes an optical device having a transparent display configured with pixels emitting display light (i.e., the heads-up display), and the transparent display has transmission regions arranged among the pixels for transmitting light representing an intensified image (e.g., luminescent light from a phosphor screen). Light rays passing through the transmission regions also pass through detectors, which detect light outside of the visible spectrum (e.g., UV light). By detecting light outside of the visible spectrum, the detectors detect the intensified image without degrading the image in the visible spectrum that is provided to users.

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 night vision system includes an intensifier with a flat exit face, an overlay display that is flat/planar, and planar, diffractive lens. The direct-view light and the display light exit the overlay display with the same phase curvature (e.g., a flat phase curvature). The planar, diffractive lens induces a spherical phase curvature on the light exiting the overlay display. The phase curvature induced by the planar, diffractive lens matches the phase curvature of a legacy intensifier in which the final element is fiberoptic inverting element with a curved exit face. Accordingly, the combination of the intensifier, overlay display, and planar, diffractive lens can replace the legacy intensifier while maintaining the design specifications of the night vision system.

Abstract: An optical system has an underlying device configured to provide output light. A transparent optical device optically coupled to the underlying device transmits light from the underlying device through the transparent optical device to display a scene. The transparent optical device includes detector elements formed in an active area to detect light portraying at least a portion of the scene. The underlying device has transparent regions formed in the active area to allow light to pass through from the underlying device to a user. The optical system further includes an image processor that processes images produced using light detected by the detector elements to identify a specific instance of light in the scene. The image processor causes display elements in the active area of the transparent optical device to display an indicator, in the scene, correlated to the specific instance of light.

Abstract: An optical device includes an underlying device configured output light in a first spectrum. A stacked device is coupled to the underlying device is configured to be coupled in an overlapping fashion to an optical output of the underlying device. The stacked device is transparent to light in the first spectrum. The stacked device includes electro-optical circuits including: light emitters and detectors. Each detector is associated with one or more light emitters. Each detector is configured to detect light emitted from the underlying device. The light emitters are configured to output light dependent on light detected by an associated detector. Optical filters are optically coupled to an optical input of the underlying device. Each filter is aligned with a detector to suppress absorption of certain wavelengths of light by the underlying device thereby affecting light detected by the detectors and thus further affecting the light output by the light emitters.

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.
