Abstract: A system and a method for holographic storage mainly involve forming a holographic interference pattern in a holographic recording medium. The holographic storage system utilizes a light source to emit a coherent beam. The coherent beam is irradiated to a first reflector to form a divergent beam. The divergent beam is then irradiated to a second reflector to form collimating beams (a signal beam and a reference beam). The signal beam goes through a spatial light modulator (SLM) and is modulated by the SLM. After that, the reference beam and the modulated signal beam are irradiated to a convergent unit, and are directed to the holographic recording medium for forming the holographic interference pattern. The holographic storage system that the light source is split into a signal beam and a reference beam by a set of reflectors according to the reflection principle without involving refraction may employ wavelength multiplexing.

Abstract: The invention relates to a method for the calculation of a computer-generated multilayer hologram with more than or equal to 2 holograms. Field A0 of a readout beam and field AR in the reflection plane are preset as mathematical functions. Except for the hologram to be calculated, all the other holograms of the layer structure are also preset as mathematical functions. Fields Ainull/Ainull are then calculated on both sides of hologram hi, as a result of which hologram function hi is calculated by forming a quotient from fields Ainull/Ainull. The invention also relates to a method for the production of multilayer holograms as well as a holographic storage medium with a multilayer hologram produced according to this method.

Abstract: A new type of holographic recording in photorefractive crystals is disclosed, termed orthogonal data storage, in which counterpropagating, reflection mode holograms are wavelength multiplexed to form gratings lying along a common axis. It is shown that this configuration provides substantial improvements in data storage capacity in comparison to prior art systems and that higher coupling coefficients are achieved. In consequence, not only storage of data but a wide range of other devices including wavelength selective filters, lenses and optical correlation systems are disclosed. Further, methods of writing and processing metastable images are disclosed which substantially improve the strength of the gratings that are permanently developed in the medium. These methods include advantageous use of electrical potentials and photovoltaic properties, together with different interrelationships during processing.

Abstract: A holographic display includes "segmented" images configured as if positioned in separate viewing "cells" corresponding spatially to preselected subareas of a desired display area with invisible segmenting cell sides. In one embodiment, a polarized conjugate reference light source projects the segmented hologram images form a light-transmissive recording medium into the display area, a multi-element nematic 90.degree. twisted shutter assembly changes the polarization of light emanating from subareas corresponding to the images to be blocked while keeping unchanged the polarization of the segmented images to be displayed, and a sheet polarizer positioned between the multi-element shutter and the viewer blocks from view images from those subareas which the polarization direction has been changed by the multi-element shutter. In other embodiments, light-reflective recording mediums and multi-element nematic shutters having an appropriate guest-host dyes are used. Constantly viewable unsegmented holographic images recorded in the same recording medium as the segmented images or on a separate recording medium can be multiplexed into the display area using a conjugate light source of a different frequency or having a different polarization condition (e.g., unpolarized) from the conjugate light source used to project the segmented images to be selectively displayed/blocked.

Abstract: Systems, devices, and methods for eyebox expansion by exit pupil replication in wearable heads-up displays (“WHUDs”) are described. A WHUD includes a scanning laser projector (“SLP”), a holographic combiner, and an optical splitter positioned in the optical path therebetween. The optical splitter receives light signals generated by the SLP and separates the light signals into N sub-ranges based on the point of incidence of each light signal at the optical splitter. The optical splitter redirects the light signals corresponding to respective ones of the N sub-ranges towards the holographic combiner effectively from respective ones of N spatially-separated virtual positions for the SLP. The holographic combiner converges the light signals to respective ones of N spatially-separated exit pupils at the eye of the user. In this way, multiple instances of the exit pupil are distributed over the area of the eye and the eyebox of the WHUD is expanded.
