Patent number: 11940613Abstract: 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.Type: GrantFiled: October 29, 2021Date of Patent: March 26, 2024Assignee: L3HARRIS TECHNOLOGIES, INC.Inventors: Jon D.

Publication number: 20230135448Abstract: 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.Type: ApplicationFiled: November 4, 2021Publication date: May 4, 2023Inventors: Jon D.

Publication number: 20230134188Abstract: 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.Type: ApplicationFiled: October 29, 2021Publication date: May 4, 2023Inventors: Jon D.

Publication number: 20230139708Abstract: 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.Type: ApplicationFiled: October 29, 2021Publication date: May 4, 2023Inventors: Jon D.

APPARATUS AND METHOD FOR A VISION SYSTEM HAVING A TRANSPARENT DISPLAY AND A DIFFRACTIVE, PLANAR LENS
Publication number: 20230133988Abstract: 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.Type: ApplicationFiled: October 29, 2021Publication date: May 4, 2023Inventors: Jon D.
