摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a taggant by which the taggant having various identification information can be manufactured by a simple method, and can be recovered by a high recovery rate, and to provide the taggant having the various identification information.SOLUTION: The manufacturing method is used for the taggant having a base material formed of resin, and an identification layer having identification information, which is formed on the base material formed of resin, and can be observed when being magnified. The manufacturing method includes a board having identification information layer forming process, a freezing process, and a grinding process. In this case, in the board having identification information layer forming process, the board having identification information layer is formed by forming the identification information layer including the identification information on the base material made of resin. In the freezing process, the board having identification information layer is frozen. In the grinding process, the taggant having the identification layer and the base material formed of resin is formed by grinding the frozen board having the identification information layer to an observable size by magnifying the frozen board having the identification information layer. The problem is solved by providing the manufacturing method.

摘要： PROBLEM TO BE SOLVED: To present reproduction images having a wide viewing angle without distortion even when using a spatial light modulation element having a coarse pixel pitch. SOLUTION: Hologram interference fringes formed on recording surfaces 20R and 20L by an object light from an original image 10 and reference light 40R and 40L are calculated by a computer to be included in image data 50R and 50L. A right-eye and a left-eye observation positions 30R and 30L are established in advance and light is used that takes a light path that converges to these observation positions as reference light 40R and 40L. A spatial light modulation element such as a liquid display is arranged at a position on the recording surfaces 20R and 20L, respectively, and image data 50R and 50L are provided and driven to make hologram interference fringes to be displayed. On the presentation face of the interference fringes regeneration irradiation light is radiated that takes the same optical path with the reference light 40R and 40L and make an observer observe the same with both eyes ER and EL being placed at observation points 30R and 30L.

摘要： PROBLEM TO BE SOLVED: To provide a hologram recording medium that gives an observer an intuitive and peculiar visual effect. SOLUTION: Two window-like regions 11, 12 are provided on a medium 10, each having a distinct hologram recorded therein. The outer circumference of each window-like region 11, 12 is enclosed by a frame-like region 13 where a grating is formed to give a window frame appearance. When a hologram H1 recorded in the window-like region 11 is reproduced (shown in the upper side of the figure), a star-shaped three-dimensional image A1 is reproduced in front of a common three-dimensional image C as a background. When a hologram H2 recorded in the window-like region 12 is reproduced (shown in the lower side of the figure), a spherical three-dimensional image B2 is reproduced in front of the common three dimensional image C as a background. When the inside is viewed deeply through right and left window-like regions 11, 12, discrepancy of objects placed in front of the common background feature C is induced as the objects are star-shaped or spherical, giving a peculiar visual effect. Otherwise, discrepancy may be induced between positions where the three-dimensional figures are to be reproduced. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To obtain a bright reproduced image while superimposing and recording, on a medium, both a stereoscopic original image and a plane original image. SOLUTION: The plane original image composed of unit regions U1, U2 is prepared. Rectangular cells C1 with a width of 0.4 μm are arranged in the unit region U1; and rectangular cells C2 with a width of 0.6 μm are arranged in the unit region U2. Arithmetic points P1, P2 are defined at the centers of the rectangular cells C1, C2, and interference wave intensity generated by composite wave and reference wave of object light emitted from each part of the stereoscopic original image is computed on individual arithmetic point positions. A groove having an aperture area corresponding to the interference wave intensity obtained by operation is formed in an arithmetic point peripheral position in each cell. Information on the plane original image is recorded by variation of lateral pitch (variation of arithmetic point density) of the grooves formed in each unit region, and hologram interference fringe of the stereoscopic original image is recorded by the distribution of aperture areas of the grooves.

摘要： PROBLEM TO BE SOLVED: To provide a process with which a multi-image type hologram wherein one 3D image changes over to other depending on a viewing direction can be fabricated with simple construction and a multi-image type hologram fabricated by the process. SOLUTION: According to the process for the fabrication of a multi-image type hologram wherein one image changes over to other depending on a viewing direction, the area of a hologram recording material is divided into a plurality of sub-areas 11 1 , 11 2 and 11 3 . Objects to be displayed on different images are holo-graphically recorded in the respective sub-areas, using reference light having the same angle of incidence, thereby recording them as the first-stage hologram 11. Object images O 1 ', O 2 ' and O 3 ' recorded in the respective sub-areas 11 1 , 11 2 and 11 3 are simultaneously reconstructed from the recorded first-stage hologram 11, so that a second-stage hologram recording material 21 is located near the reconstructed object images O 1 ', O 2 ' and O 3 ' for recording them as a reflection or transmission type volume hologram.
