摘要： A holographic direct-view display system uses holographic integral imaging techniques that is an auto stereoscopic way to reproduce parallax and occlusion. The display is not resolution limited and is scalable to display life size images if desired. The system can be used to transmit 3D depictions of a scene at video and sub-video rates as well as other information, such as images of documents or computer generated images. The images may be captured, transmitted and displayed in real-time (or near real-time) for telepresence or stored for time-shifted display. The system combines integral holography, a pulsed laser to record the hologram at high speed and a dynamic refreshable holographic material such as a photorefractive polymer as a recording media. The system uses techniques to write, read and erase the updateable hologram that allow the holographic material, hence direct-view display to remain stationary throughout each of the processes for continuous presentation of the hologram to the audience. The system may write, read and erase at the same time and continuously to increase throughput. This system may also use additional novel techniques to improve brightness, efficiently implement a full-parallax display and to implement a full-color display in a transmission geometry.

摘要： A hybrid strip-loaded EO polymer/sol-gel modulator in which the sol-gel core waveguide does not lie below the active EO polymer waveguide increases the higher electric field/optical field overlap factor Γ and reduces inter-electrode separation d thereby lowering the modulator's half-wave drive voltage Vπ, reducing insertion loss and improving extinction. The strip-loaded modulator comprises an EO polymer layer that eliminates optical scattering caused by sidewall roughness due to etching. Light does not encounter rough edges as it transitions to and from the sol-gel and EO polymer waveguides. This reduces insertion loss.

摘要： A system and method that synchronizes a spatial light modulator (SLM) with a pulsed laser to record a hologram at the repetition rate of the pulsed laser for applications including holographic displays and data storage. The color channel capability of a SLM is utilized to effectively increase the write throughput when the pulsed laser repetition rate LR exceeds the SLM's image refresh rate R. The hogels are encoded on the color channels and concatenated to form a sequence of color images such that the write throughput is equal to the repetition rate LR up to a maximum of N*R. The invention effectively extends the capability and continued viability of existing inexpensive SLMs.

摘要： An updateable system and method of recording a hologram on a media simultaneously reduces the writing time and increases persistence without sacrificing diffraction efficiency. A voltage kick-off technique controls the bias electric field applied to a photorefractive polymer media in conjunction with the application of the writing beams and dark decay. Essentially the voltage kick-off technique applies a high electric field above the optimal field while the writing beams are on and reduces the electric field when the writing beams are off during dark decay. The voltage kick-off technique produced two separate unexpected results. First, when the writing beams are turned off and the electric field is lowered the diffraction efficiency continues to increase until it reaches a maximum efficiency that is within a few percent of that achieved by writing at the optimal field until steady-state is achieved. Second, the decay time constant is much larger than expected producing a much longer persistence without sacrificing diffraction efficiency or writing time.

摘要： Optical switch based on a micro-minor device such as a DMD configured to simultaneously switch light from N inputs to M outputs with switching times of about 10 microseconds, where N and M are generally greater than one. The minors of the device are oriented according to a pattern calculated based on a Fourier Transform of spatial distribution of M outputs such as to form, in diffraction of light incident on the device, and diffraction light pattern that in the output plane is substantially congruent with the spatial distribution of M outputs. The device can be configured as a modulator of amplitude and/or a modulator of phase of incident light wavefront.
