Patent number: 9760061Abstract: Methods and systems for performing dynamic aperture holography are described. Examples include a method of recording multiple holograms in a photosensitive recording medium, where multiple signal beam angular apertures used to record the multiple holograms differ from each other. The multiple signal beam angular apertures can facilitate using a larger range of reference beam angular apertures. The multiple holograms are typically multiplexed, and examples of dynamic aperture holography enable packing the multiplexed holograms more densely in the recording medium. Some dynamic aperture holography systems include monocular objective lens architecture.Type: GrantFiled: March 21, 2014Date of Patent: September 12, 2017Assignee: AKONIA HOLOGRAPHICS LLCInventors: Mark R.

Patent number: 6100945Abstract: A display system for acting on light entering the system includes a reflective ferroelectric liquid crystal spatial light modulator and a polarizer arrangement. The polarizer arrangement includes a polarizer for polarizing the light entering the system and directing the polarized light into the spatial light modulator along an optical path having an optical path axis. The reflective spatial light modulator acts on the polarized light to produce an optical output that is directed from the spatial light modulator back into the polarizing arrangement along substantially the same optical path axis that the polarized light is directed into the spatial light modulator. The polarizing arrangement also includes an analyzer configured to receive and analyze the optical output of the spatial light modulator and to direct the analyzed optical output out of the system.Type: GrantFiled: February 17, 1999Date of Patent: August 8, 2000Assignee: Displaytech, Inc.Inventors: Charles M.
