  • Patent number: 10404403
    Abstract: Free-space communication systems and methods are provided. The systems include a transmitter that combines multiple sets of radio-frequency-modulated optical carrier frequencies for transmission across free space using multiple transmission apertures. Different sets of signals are filtered to form single sideband signals. The different sets of single sideband signals are then combined to form dense wavelength division multiplexed signals. In addition, combined sets of signals of different polarizations can be combined. A receiver can include a single receive aperture.
    Type: Grant
    Filed: March 14, 2018
    Date of Patent: September 3, 2019
    Assignee: Ball Aerospace & Technologies Corp.
    Inventors: John R. Troeltzsch, Colin H. Wilson, Robert M. Pierce, Holden Chase, Brian Primeau, Robert Kaliski, Bevan D. Staple, Robert Marshalek

  • Patent number: 8130439
    Abstract: A system for producing modulated lights disclosed. The system comprises a spatial light modulator including a light modulating medium switchable between different states so as to act on light in ways which form overall patterns of modulated light. The system also includes an arrangement for switching the modulating medium between the different states in a controlled way and an illumination arrangement for producing a source of light. The system, further includes an optics arrangement for directing light from the source of light into the spatial light modulator and for directing light from the spatial light modulator through a predetermined source imaging area. The optics arrangement cooperates with the illumination arrangement and the spatial light modulator so as to produce a real image of the source of light within the source imaging area such that an individual is able to view a virtual image of the overall patterns of modulated light from the source imaging area.

  • Patent number: 6025890
    Abstract: A display system includes a reflective mode spatial light modulator for producing a pattern of polarized light, a light source for illuminating the spatial light modulator, and an optics arrangement. The optics arrangement includes a beam splitter element having a transparent substrate with a front face and a back face. The front face supports a beam splitter coating acting as a beam splitter. The back face supports a polarizer layer. The polarizer layer and the transparent substrate are configured to be refractive index matched to prevent the reflection of light at the interface between the transparent substrate and the polarizer layer. The beam splitter element is positioned in the optical path between the light source and the spatial light modulator in order to polarize and direct light from the light source to the spatial light modulator.
