| PURPOSE:To obtain a sharper stereoscopic reproduced image in a dark room state by providing a phosphor layer on the reverse surface of a transmission type hologram. CONSTITUTION:Laser light 1 is partially reflected by a beam splitter 4 with high transmissivity and the majority is transmitted. The transmitted light 3 is reflected by a mirror 8 and a mirror 9, expanded through an objective lens 11 and a pinhole 13, and collimated by a collimator lens 14 into parallel light, which irradiates the base surface of a master hologram, thereby reproducing a real image on a recording dry plate 16 for a hologram. The reflected light 2 from the beam splitter 4, on the other hand, is reflected by a mirror 5 and a mirror 6, expanded through an objective lens 10 and a pinhole 12, and reflected by a mirror 7 to strike on the emulsion surface of the recording dry plate 16 for the hologram as reference light through frosted glass 17 placed as close to the recording dry plate 16 as possible, thus manufacturing the hologram. | ||||||

| PURPOSE: To produce the hologram having a high degree of freedom of use by irradiating the original plate of a master hologram with the divergent light made by an objective lens through a slit and a diffusion plate in contact with the slit as well as a subject in this order and irradiating the master plate with the collimated beams of light formed by a collimating lens as reference light, thereby generating interference fringes and executing recording. CONSTITUTION: One of the split laser beams bisected by a beam splitter 2 is collimated by a meter lens 7 and the master plate 11 of the master hologram is irradiated with the collimated beams 8 of light as the reference light. The other laser beam is reflected by a mirror 3b and is made incident to the objective lens 4b. The beam is made into the divergent light by the objective lens 4b and is made incident to the slit 5 mounted on the diffusion plate 6. The slit 5 selects a specific wavelength. The incident divergent light to the slit 5 is diffused by the diffusion plate 6 and is projected to the subject 10. The original plate 11 of the master hologram is irradiated with the light transmitted through the subject. The hologram for reconstruction of a wide area is obtd. by the small-sized objective lens 4c from the master hologram produced by this method. The hologram for reconstruction having the wide area is obtd. with the optical system of the low cost in this way. COPYRIGHT: (C)1991,JPO&Japio | ||||||

| A hologram (and related hologram element) contains and exhibits a holographic image when illuminated and viewed on angle and with the holographic image gradually fading when viewed increasingly off angle in 1st-3rd directions. This hologram also contains and exhibits a monochrome wash surface that obscures (partially or totally) the holographic image when viewed in a 4 th direction as the hologram is increasingly rotated off angle in a 4th direction through a range of angles. The hologram can be fabricated with a variety of color choices for the monochrome wash surface. The hologram is useful in security and authentication applications and is used in a method provided herein for authentication of an article. | ||||||

A multicolor hologram display structure which is capable of presenting an intermediate color with high reproducibility and which requires a relaxed accuracy for alignment between hologram original plates of different colors. The multicolor hologram display structure has at least two multi-recorded or superimposed volume holograms that diffract light of different wavelengths, e.g. red light and green light, respectively. The multicolor hologram display structure includes an intermediate color pattern region consisting essentially of dots (7) formed from two of the at least two multi-recorded or superimposed holograms and a background (8) of either of the two holograms that is recorded between the dots. A region of the volume holograms may be subjected to color tuning to reproduce a color different from the recorded color.

An inline type speckle multiplexed hologram recording apparatus and method is disclosed which can condense signal light and reference light in a sufficiently overlapping relationship with each other on a hologram recording medium without using a lens having a large aperture and a wide angle of view. A signal light region and a reference light region are displayed on a spatial light modulator (1), and laser light is intensity modulated with recording data displayed in the signal light region to produce signal light (100) while the laser light having passed through the reference light region is used as reference light (200). The signal light and the reference light are diffused by a diffuser (2) and then condensed in an overlapping relationship with each other on a hologram recording medium (4) by a lens (3) such that interference fringes produced thereby are recorded in the hologram recording medium.

| Certain types of holographic recording materials can be used to updateably record holographic stereograms formed when fringe patterns are generated through interference of an object laser beam containing image information with a reference laser beam. In this manner, calculation of fringe patterns is avoided, and instead perspective information is computed for a scene or object to be displayed, the information is downloaded to display hardware such as a spatial light modulator, and fringe patterns are subsequently generated through interference of an object laser beam containing this information with a reference laser beam in the classic hologram recording scheme. Previously recorded holographic stereograms or component hogels are updated by erasing the stereograms or component hogels and recording updated stereograms or component hogels, or by recording updated stereograms or component hogels in a separate portion of the holographic recording material. | ||||||

| This invention relates to reconfigurable spatial light modulators (SLM) incorporating a scatter plate (5). Computer generated diffraction patterns or holograms may be loaded on the (SLM) either as a single frame or as a series of frames for observation by an observer. In a preferred embodiment both an electrically addressable spatial light modulator (EASLM) and an optically addressable spatial light modulator (OASLM) are used. The (OASLM) may be formed of several smaller (OASLMs) arranged in a matrix format. The faster (EASLM) forms a light pattern on sub-areas of the large (OASLM) in turn to give a large display. The scatter plate (5) is arranged at the output of the (SLM) nearest an observer. This scatter plate has a known characteristic and serves to increase the field of view and/or reduce the number of pixels required to give a holographic or two dimensional displays. Prior to producing a display, the diffraction patterns, holograms, or image in the computer is modified to take account of the properties of the scatter plate; a modified computer generated diffraction pattern, hologram, or image is then displayed to an observer. The system may also be used for optical switching. | ||||||

In the method for producing holograms, a plurality of images displayed on a spatial optical modulating element 6 is used as the object light. Through a lens array 7 composed of a plurality of lenses disposed corresponding to each of the images, which are included in the object light, and a reducing optical system 9 and 10 for reducing the object light emitted from the lens array 7, the object light is made to irradiate a recording surface 11 along with a reference light; thereby interference light between the object light and the reference light is recorded on the recording surface 11. Between the spatial optical modulating element 6 and the lens array 7, partitions 15 for separating the respective images are provided; thereby noise is reduced. |

A plurality of photo-sensitive members are independently exposed to obtain respective holograms, which are connected by using an adhesive layer 80 constructing a connecting means, in order to obtain an integrated hologram expanded in two-dimensional direction. The holograms are obtained by an interference of a reference light 22 and an object light passed through a light diffusing body 24 in order to cause the light diffusing body 24 to be recorded on the photo-sensitive member. The size of the light diffusing body 24 is such that the spectral characteristic of the diffused light from the hologram can attain a desired efficiency at least over the entire wavelength range of the visible light. |
