Abstract: The pupil formed by an optical apparatus is expanded by use of a beam splitter to replicate the pupil and a waveguide to further replicate the replicated pupil. An optional rotator element can rotate a portion of the light split by the beam splitter to provide consistent polarization of light in the optical apparatus. In some embodiments, the beam splitter replication expands the pupil in one direction, while the waveguide replication expands the pupil in a second direction.

Abstract: A system and method for operating an electronic device used in light processing. A method comprises altering a spatial relationship between a spatial light modulator (SLM) and a light incident on the SLM, shifting light modulator states of a first portion of light modulators to a second portion of light modulators, and placing a third portion of light modulators in the SLM into a performance degradation-reducing mode. The amount of shifting performed is proportional to the amount of change in the spatial relationship. The method allows for a change in light modulators used to modulate the light, thereby preventing the overuse of some of the light modulators, which may help to prevent degradation of the light modulators. The performance degradation reducing mode may help to further reduce or even reverse the performance degradation of the light modulators.

Abstract: System and method for using predictive pulse modulation in display applications. A preferred embodiment comprises sampling a light output of a light source, computing a usage history of the light source, and processing the samples of the light output in combination with the usage history to characterize the light source. The characterization of the light source can be used in conjunction with a desired light output to determine a current pulse waveform to provide to the light source to have the light source produce the desired light output. The characterization of the light source can occur during normal use of the display system or during manufacture or setup and configuration of the display system.

Abstract: Disclosed is a method for generating patterns to be used in a spatial light modulator having a plurality of pixels. The method includes generating an optical pattern to be placed upon the pixels of the spatial light modulator, applying the optical pattern to the pixels of the spatial light modulator, measuring the optical performance of the plurality of pixels having the optical pattern applied to it, comparing the measured optical performance to a target optical performance, and adjusting the optical pattern applied to the plurality of pixels to form another optical pattern that more closely achieves the target optical performance.

Abstract: A programmable amplifier 100 operable to independently adjust the amplification given to various optical signals passing through an optical fiber. An input optical fiber 102 provides a number of optical signals to a demultiplexer which separates each signal carried by the input fiber 102. Each individual wavelength travels to a variable attenuator 106 which lowers the signal strength of each signal based on an input from the system controller 108. The attenuated signals are combined by multiplexer 112 and input to an optical amplifier 114. The optical amplifier 114 receives the combined signal and amplifies each signal in the combined DWDM signal across the entire bandwidth of the amplifier 114. The amplified signals are input to a splitter 116 which removes a small portion of the entire spectrum output by the amplifier 114. The remaining portion of the signal passes to an output fiber 110 and travels to the remainder of the optical network.
