  • Patent number: 11294113
    Abstract: A compound retarder that creates independent control of Re and Rth. This can be done by forming a three-layer compound retarder, including a pair of matched ?A-plates, combined with single +A-plate. The +A-plate is typically an MD-stretched film, with retardation that is specific to the in-plane requirements (Re) of the application. The pair of ?A-plates have their optic axes crossed, such that Re=0, with an optic axis aligned parallel to the +A-plate. A single retardation value for the ?A-plate can produce improved field-of-view performance over a broad range of Revalues, making it a very practical means of universal compensation. While Rthis typically associated with a single retarder, retarder stacks with a diverse range of optic-axis orientations can be considered to have a compound (or composite) Rth value (RthC). The three-layer compound retarder has the practical benefit of enabling field-of-view compensation across a broad range of normal-incidence polarization transformations.

  • Patent number: 9631973
    Abstract: A programmable multifunction spectral and/or polarization imager. In one example, such an imager includes an imaging optical subsystem configured to receive electromagnetic radiation from a distant scene, a focal plane array configured to produce an image of the scene, and a programmable polarimetry subsystem electrically switchable between an ON state in which the polarimetry subsystem receives the electromagnetic radiation and provides polarized electromagnetic radiation to the focal plane array, and an OFF state in which the polarimetry system is configured as a first substantially clear aperture that passes the electromagnetic radiation to the focal plane array. In certain examples, the imager includes a programmable spectral imaging sub-system configurable between an ON state and an OFF state.

  • Patent number: 9316865
    Abstract: An optical shutter (10) includes a wavelength selective polarizing filter (12) in optical association with a liquid crystal polarization modulator (14) to rapidly switch between optical states to alternately transmit visible radiation and near infrared radiation. The wavelength selective polarizing filter is constructed to impart a polarization state to incident radiation and transmit polarized radiation within at least the visible wavelength region of the electromagnetic spectrum. The liquid crystal polarization modulator is positioned to receive incident radiation for internal propagation through the liquid crystal polarization modulator and is responsive to a first value and a second value of an applied control signal (32) to switch the internally propagating radiation to, respectively, a first polarization state and a second polarization state.

  • Patent number: 8780014
    Abstract: A head-mounted display apparatus includes a head-mounted display, the head-mounted display including a plurality of independently controllable switchable viewing areas that can each be independently switched between a transparent state and an information state. The transparent state enables a user of the head-mounted display to see the scene outside the head-mounted display through the independently controllable switchable viewing areas. The information state is opaque and displays information in the independently controllable switchable viewing areas visible to a user of the head-mounted display. Circuitry produces a control signal for controlling the states of the independently controllable switchable viewing areas and a controller responsive to the control signal independently switches each of the independently controllable viewing areas between the transparent state and the information state.
