    Abstract: A holographic substrate-guided wave-based see-through display can has a microdisplay, capable of emitting light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the image from the microdisplay, and capable of transmitting the light. The holographic optical element couples its output to an elongate substrate, capable of accepting the light from the holographic lens at a first location, and transmitting the light along a length of the substrate by total internal reflection to a second location, the elongate substrate being capable of transmitting the accepted light from the second location. The substrate couples out what it receives to a transparent holographic optical element, capable of accepting the light transmitted from the substrate and transmitting it to a location outside of the holographic optical element as a viewable image.

    Abstract: A large coherent two-dimensional (2D) spatial filter array (SFA), 30 by 30 or larger, is produced by coupling a 2D planar lightwave circuit (PLC) array with a pair of lenslet arrays at the input and output side. The 2D PLC array is produced by stacking a plurality of chips, each chip with a plural number of straight PLC waveguides. A pupil array is coated onto the focal plane of the lenslet array. The PLC waveguides are produced by deposition of a plural number of silica layers on the silicon wafer, followed by photolithography and reactive ion etching (RIE) processes. A plural number of mode filters are included in the silica-on-silicon waveguide such that the PLC waveguide is transparent to the fundamental mode but higher order modes are attenuated by 40 dB or more.

    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.
