    Abstract: A transparent holographic diffuser screen that diffracts the light beams of a digital light projector, which focuses a real image in the plane of the aforementioned transparent holographic diffuser screen, which redirects the light to an eyebox at a pre-determined viewing position generating as a set of diffracted diffused beams that can be seen from the eyebox as a flat in-plane image. The transparent holographic diffuser screen may be used to provide either a highest luminance or a largest eyebox. Potential applications include use for automotive applications, which may include applications for displaying videos, playing games, and video conference apps.

    Abstract: The Compound Eye Laser Illumination Seeker is a tracking system used to guide items to point at a laser-illuminated target, with the illumination being either pulsed or modulated at either a specific rate or within a range of rates. The device comprises a multiaperture compound receiver optics to collect the signal, a set of light guides to combine the received light into light representing individual angular sectors and redirect it to detectors whose output represents the illumination signal in that quadrant, a spectral filter, an angle filter, the set of detectors, and processing electronics. The output is an electronic signal indicating the angular difference between the pointing direction of the signal and the pointing direction of the tracking device.

    Abstract: Systems and methods for reducing glare from a heads-up display (HUD). Internal and external antireflective coatings may be provided on interior and outer surfaces of glass layers surrounding a holographic polymer layer. A substrate guided hologram may be integrated into a HUD to diffract and direct external radiation to the edge of a HUD. An arrangement for forming a substrate guided hologram includes an array of reflectors and a shaped glass block. Antireflective coated glass layers may be index-matched to opposite sides of a holographic polymer film prior to recording a reflection hologram. An inactive playback beam may be used to monitor the diffraction efficiency of a reflection hologram and of a spurious transmission hologram with the recording of the reflection hologram to maximize the difference between the diffraction efficiencies of useful reflection hologram and spurious transmission hologram.

    Abstract: The Compound Eye Laser Illumination Seeker (CELIS) is a tracking system used to guide items to point at a laser-illuminated target, with the illumination being either pulsed or modulated at either a specific rate or within a range of rates. The CELIS, comprising a multiaperture compound receiver optics (MACRO) to collect the signal, a set of light guides to combine the received light into light representing individual angular sectors and redirect it to detectors whose output represents the illumination signal in that quadrant, a spectral filter, an angle filter, the set of detectors, and processing electronics. The output is an electronic signal indicating the angular difference between the pointing direction of the signal and the pointing direction of the tracking device.
