摘要： A method of producing a big size holographic screen for projection of the stereoscopic or multiview 3-dimensional color images is proposed, where a narrow and elongate slit-shaped diffuser is recorded on the hologram as an object to ensure the well defined viewing zone forming in course of the image projection. As compared with the previous art the diffuser length is increased by the calculated value to provide undistorted color reproduction on whole screen surface. The parameters required for the recording of the holographic screen, including the position of a photoplate with respect to the diffuser, the position of a reference wave point source with respect to the diffuser, the distance from which an image is observed and so on are determined by consideration of the phase relationships between the reference, object, projector and reconstructed waves on the photoplate surface.

摘要： A video image F�k! is identified as a basis image and stored as a basis page S�k! in a holographic storage medium. A subsequent image F�k+n! is stored by recording in the medium a page S�k+n!=F�k+n!-a�k!F�k!, where a�k!.noteq.0 and preferably a�k!=1. The page S�k! is recorded with a reference beam R�k!, while S�k+n! is recorded with a reference beam R�k+n! orthogonal to R�k!. The basis page is reset whenever the average intensity of a page to be stored exceeds a predetermined threshold. An image F'�k! is retrieved by reading basis page S�k! and letting F'�k!=S�k!. Subsequent images F'�k+n! are retrieved as S�k+n!+b�k!S�k!, where b�k!.noteq.0 and preferably b�k!=a�k!=1. The page addition step is performed coherently, i.e. by accessing the medium with a reference wave function R�k+n!+b�k!R�k!. The coherent addition is achieved by using a compound phase-and-amplitude modulator in a phase-code-multiplexed system, and by simultaneously accessing the storage medium at two different angles in an angle-multiplexed system. Differential video compression leads to a reduction in interpage crosstalk and to a capacity increase in crosstalk-limited memories. Optical page-by-page addition allows fast readout and eliminates the need for a time-consuming electronic decompression step.

摘要： A laser beam is reflected by a light beam scanning device and irradiated onto a hologram recording medium. On the hologram recording medium, an image of a linear scatter body is recorded as a hologram by using reference light that converges on a scanning origin. The light beam scanning device bends the laser beam at the scanning origin and irradiates the laser beam onto the hologram recording medium. At this time, by changing a bending mode of the laser beam with time, an irradiation position of the bent laser beam on the hologram recording medium is changed with time. Diffracted light from the hologram recording medium produces a reproduction image of the linear scatter body on a light receiving surface of the stage. When an object is placed on the light receiving surface, a line pattern is projected by hologram reproduction light, so that the projected image is captured and a three-dimensional shape of the object is measured.

摘要： Disclosed herein are a multifunctional optical element and method using multiple light scattering. An optical control method using multiple light scattering may include the steps of splitting coherent light into a signal beam and a reference beam, controlling the wavefront of the signal beam, forming an interference pattern by making the signal beam having the controlled wavefront and the reference beam incident on photorefractive materials, recording the interference pattern on the photorefractive materials, reconstructing the signal beam having the controlled wavefront by the interference pattern by radiating the reference beam to the photorefractive materials on which the interference pattern has been recorded again, and controlling the properties of light passing through complex media based on multiple light scattering generated by the complex media as the reconstructed signal beam is incident on the complex media.

摘要： The present invention is directed toward a system and method for projecting holographic optical traps whose intensity maxima are extended along specified paths in three dimensions with specified amplitude and phase profiles along those paths. Specifying paths that constitute knotted loops and phase profiles that direct radiation pressure along the knotted paths yields optical traps that exert knotted force fields. Knotted optical force fields have uses for inducing motion along knotted paths, with applications including the generation of knotted electric current loops in plasmas.
