Abstract: Display devices can be used to provide display functionality in dynamic autostereoscopic displays. One or more display devices are coupled to one or more appropriate computing devices. These computing devices control delivery of autostereoscopic image data to the display devices. A lens array coupled to the display devices, e.g., directly or through some light delivery device, provides appropriate conditioning of the autostereoscopic image data so that users can view dynamic autostereoscopic images. Methods and systems for calibrating a hogel display are also described, including generating calibration hogel data corresponding to a calibration pattern; generating a hogel light field from the calibration hogel data; detecting the hogel light field; and determining calibration data by analyzing a set of hogel properties in response to detecting the hogel light field.

Abstract: An apparatus is disclosed that includes a transparent support structure having an upper surface and a lower surface. The lower surface is configured to be supported by one or more outer walls of a display module. The upper surface is configured to support imaging optics associated with the display module. The upper surface coincides with an imaging plane associated with the display module. The thickness of the transparent support structure is selected to permit light entering the lower surface proximate to the one or more outer walls to pass through to the upper surface and reach the outer edge of the one or more outer walls without being substantially blocked.

Abstract: An optical device for processing an optical signal includes a crystal wedge, a polarization modulator, and a reflective element. The crystal wedge spatially separates an input optical signal into a first beam component having a first polarization state and a second beam component having a second polarization state. The crystal wedge has an optical axis arranged at an optical axis angle such that the first beam component and the second beam component converge. The polarization modulator changes the polarization state of the first beam component and the polarization state of the second beam component in response to a control signal. The reflective element reflects the first beam component and the second beam component such that the crystal wedge spatially recombines a portion of the first beam component having the second polarization state with a portion of the second beam component having the first polarization state to form an output optical signal.

Abstract: Devices and methods for equalizing the gain of an optical amplifier are described. For devices including harmonic filters that are controllable by amplitude control voltages and phase control voltages, techniques for controlling the amplitude control voltages and phase control voltages are presented. Additionally, device architectures are described by which an incoming optical signal is equalized to compensate for uneven gain in prior amplifiers or other optical components, and in which the incoming optical signal is received at a beam displacer and separated into orthogonal component beams, wherein the beams are counter-propagated through the equalizer in opposite directions through the same spatial path so as to minimize or eliminate the effects spatially dependent imperfections in the equalizer.

Abstract: An optical equalizer for use primarily with an erbium-doped fiber amplifier has an initial polarizer that convert the input beam to a predetermined polarization, followed by a series of dynamically-adjustable sinusoidal filters that provide attenuation as a sinusoidal function of beam wavelength. Each of the sinusoidal filters has a first liquid crystal cell adjustably rotating the polarization of the beam from the preceding polarizer. This is followed by a second optical element that retards the beam as a sinusoidal function of beam wavelength. For example, the second optical element can be a birefringent crystal that provided a fixed degree of retardance to the beam and a second liquid crystal cell that provides a variable degree of retardance, thereby allowing adjustment of the center frequency of the sinusoidal function. Finally, a third liquid crystal cell adjustably rotates the polarization of the beam.
