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： Coherent light from laser 210 is magnified, made into a parallel light flux LL and irradiated on the hologram recording medium 220 in which a hologram image of a scatter plate is recorded. A hologram reproduction real image 235 of the scatter plate is generated using the parallel light flux LL as illumination light for reproduction. The spatial light modulator 240 consisting of a liquid crystal display, etc., is disposed so as to overlap on the position of the hologram reproduction real image 235, and a modulated image is obtained on the surface of the reproduction real image 235 of the scatter plate. The modulated image is projected onto the screen 260 by the projection optical system 250. The distribution angle of incident light θ incident into one point Q1 on the screen 260 is made into 0.4 degrees or more, the hologram recording medium 220 is caused to cyclically make a motion in the XY-plane by a motor 225, and the linear speed of light scanning on the screen 260 is made into 200 mm or more per second.

摘要： Disclosed is a multiplexing method and apparatus that allows holograms to be spatially multiplexed with partial spatial overlap between neighboring stacks of holograms. Each individual stack can additionally take full advantage of an alternate multiplexing scheme such as angle, wavelength, phase code, peristrophic, or fractal multiplexing, for example. An amount equal to the beam waist of the signal beam writing a hologram separates individual stacks of holograms. Upon reconstruction, a hologram and its neighbors will all be readout simultaneously. An filter is placed at the beam waist of the reconstructed data such that the neighbors that are read out are not transmitted to the camera plane. Alternatively, these unwanted reconstructions can be filtered out with an angular filter at an intermediate plane in the optical system that has a limited angular passband.

摘要： A sight assembly for mounting to a weapon. A holographic optical element and a light source are in a fixed angular configuration with respect to one another, but may be adjusted either together or individually in a horizontal or vertical direction. The sight assembly may have a mirror or lens. An adjustment mechanism is provided where a shaft includes at least two portions wherein the two portions of the shaft of the screw have different pitch directions and/or pitch dimensions allowing for slight adjustment the assembly. The light source may be a vertical-cavity surface emitting laser (VCSEL). A temperature sensor may sense a temperature of the VCSEL. A current to the VCSEL may be adjusted based on a change in the temperature such that the output wavelength is approximately the same as a desired wavelength. The assembly may further allow for perceived image distance adjustment using parallax mismatch.

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.
