    Abstract: Systems and methods for creating an autostereoscopic display include a holographic optical element (HOE) recorded using coherent light divided into diverging reference and object beams that illuminate the HOE from opposite sides. The object beam passes through first and second diffusers with one diffuser being a directional diffuser to more uniformly illuminate the HOE. Optic elements may be used to more closely match beam diameters and/or profiles of the recording wavelengths. Baffles may be positioned on opposite sides of the HOE with openings aligned proximate the reference beam and object beam paths, respectively, to reduce stray reflections and provide ambient air flow attenuation or damping. One or more edges of the HOE are masked to reduce or prevent stray light from entering and reflecting within the HOE during recording.

    Abstract: Technologies are generally described for reproducing holographic images by causing a photo-induced change in the diffractive index of a holographic recording medium. An example device may include a light irradiation unit and a transparent substrate. The light irradiation unit can be configured to transmit a photo-inducing light. Further, the transparent substrate may have a predetermined refractive index and can be configured to include a first surface and a second surface opposite the first surface. The first surface can be configured to receive an incident light, and the second surface can be configured to receive the photo-inducing light. The transparent substrate can be configured to form interference fringe patterns from a photo-induced change in the refractive index of the transparent substrate responsive to the photo-induced light.

    Abstract: A means for optically coupling a semiconductor laser to an optical fiber is disclosed. In one embodiment, a volume phase holographic element is disposed on a light-emitting surface of a semiconductor laser. The volume phase holographic element acts as an aberration-corrector for a lens that is disposed between the semiconductor laser and the optical fiber. In this way, an inexpensive lens that is not aberration free can be used. In some embodiments, the volume phase holographic element converts a Gaussian light beam emitted by the semiconductor laser into an annular beam that is more suitable for long distance transmission in multimode fibers.

    Abstract: A method of digitally processing light waves passing through a planar structure having given functions ƒin(x, y, ω) and ƒout(x, y, ω) and consisting of a light-propagating and distributing layer is provided. This layer contains a plurality of interconnecting pattern elements of a holographic pattern and a plurality of planar optical elements arranged in a predetermined pattern on the aforementioned light-propagating and distributing layer. The method consists of calculating positions and shapes of the interconnecting pattern elements of the holographic pattern based on the aforementioned given functions by solving an inverse problem. The interconnecting pattern elements have refractive indices different from the refractive indices of the light-propagating and distributing layer and are manufactured on the basis of the results of the calculations. The aforementioned continuous function is digitized, and the obtained digitized planar holographic pattern is used for converting the function ƒin(x, y, ω) into the function ƒout(x, y, ω).
