Abstract: Processes and systems are described that can produce images including both three dimensional holographic images and two dimensional variable data, which can provide personalized security features in a document. A photosensitive film can be pressed against a first reflective optical device. A laser beam can be directed through a selected first area of the photosensitive film onto the first reflective optical device to produce a three dimensional holographic image in the photosensitive film. A previously masked second area of the photosensitive film can be pressed against a second reflective optical device. The laser beam can project an image constructed by a spatial light modulator and can be directed through the second area of the photosensitive film onto the second reflective optical device to produce a two dimensional image in the second area. During the process, the web tension of the photosensitive film is controlled.

Abstract: A hologram recording device (100) includes parameter setting means (19), shifting means (20), and control means (18). The parameter setting means (19) modifies parameters for multiplex recording such as a recording angle and a focal depth relating to at least one of signal light (L3) and reference light (L2) and can fix the parameters. The shifting means (20) relatively shifts the focusing position of the signal light and the reference light with respect to a hologram recording medium in the direction along the recording surface. The control means (18) performs control so that the last multiplex recording parameter used for recording at the m-th focusing position is used as the first multiplex recording parameter for recording at the m+1-th focusing position.

Abstract: The invention relates to a fixture for supporting objects and is characterized by two plates (11, 12) which are attached rigidly and permanently to one another and of which, when the fixture is placed on a horizontal support surface, a first plate (11) will form a relatively small angle with a vertical plane, which angle will be substantially different to 0°, whereas the second plate (12) will form a relatively large angle (beta) with a vertical plane, which angle will be substantially different to 90°. The plates are provided with holes (121, 122) for receiving pegs for supporting abutment with an object.

Abstract: A hologram recording assembly (10) includes a trans­parent, absorbent member (12) supported on a substrate (14). The transparent member (12) is positioned to be directly incident to an exposure beam (A₁, A₂). The transparent member (12) is out of moisture equilibrium during an exposure time. Consequently, the transparent member (12) increases or decreases in thickness (S) depending on a moisture difference between it and the environment (28). As the thickness (S) changes, a phase shift (A₁°, A₂°) in the light reflections within the recording assembly (10) blurs spurious holograms while leaving the desired hologram intact.

Abstract: There is disclosed a high precision positioning apparatus capable of realizing accurate positioning of a recording medium with respect to an optical system by minute movement at a relatively low cost. The high precision positioning apparatus comprises a driving unit (1) for minutely moving a flat-plate shaped recording medium (10), which records/ reproduces information using light, with respect to an optical system in an in-plane direction of the recording medium (10). The driving unit (1) comprises a frame-shaped unit body (2), a first drive frame (3) accommodated inside the unit body (2), and a second drive frame (4) accommodated inside the first drive frame (3) and fixed in the vicinity of a recording portion (11) of the recording medium (10). The first drive frame (3) freely moves with respect to the unit body (2) by means of micro-driving elements (5) in an in-plane direction of the recording medium (10), and the second drive frame (4) freely moves with respect to the first drive frame (3) by means of micro-driving elements (5) in an in-plane direction of the recording medium (10), in a direction substantially perpendicular to the direction in which the first drive frame (3) moves. Therefore, the recording medium (10) is minutely moved in an in-plane direction thereof.

Abstract: A hologram recording apparatus (100) includes a record angle change device (19) capable of relatively changing the record angle of a hologram recording medium (200) relative to signal light (L3) and reference light (L2); and a control device (18). The control device sets a record angle for recording a specific angle record plane as a standard record angle among a plurality of angle record planes on the hologram recording medium. Furthermore, the control device controls the record angle change device so as to change and fix the record angle after then by a predetermined angle from the set standard record angle.

Abstract: A hologram recording plate, which has a plastic layer (a rosin derivative) that undergoes frost deformation by being acted upon by a solvent vapor, is set in a developing box supplied with a solvent vapor (cyclohexane) from a solvent vapor reservoir. The solvent vapor is exhausted from the developing box by a suction device. This is followed by subjecting the hologram recording plate to a high voltage from a high-voltage power supply and irradiating the plate with laser light, which represents a hologram to be formed, by opening a light shutter. This makes it possible to reduce the size of and to automate the hologram producing apparatus. The developing box and optical elements inclusive of a light source are secured to respective ones of individual carriers, and the carriers are provided so as to be free to be moved along an optical system aligning rail and fixed to the rail. A very simple and precise optical system can be constructed without using an optical bench or table having a vibration-proof structure.

Abstract: A one piece frame (10) for holding a holographic element (50) in a holographic system, and comprising a border portion (12), a seating portion (14), and a plurality of lateral positioning tabs (16). The border portion (12) forms an outside border of the frame (10), and is flexible between an open position for receiving the holographic element (50) and a closed position for holding the holographic element (50) in the frame (10). The seating portion (14) is connected to and extends inward from the border portion (12) to seat against a back surface of the holographic element (50). The lateral positioning tabs (16) are connected to and extend inward from the border portion (12), above the seating portion (14), and are spaced apart from each other along the border portion (12) to hold the holographic element (50) therein spaced from said border portion (12). The border portion (12) is biased toward the closed position to hold the holographic element (50) against the lateral positioning tabs (16) in a fixed position in, and with a preset angular orientation relative to, the frame (10), and to cooperate with the holographic element (50) to maintain the frame (10) in a fixed preset shape to facilitate placing and holding the holographic element (50) in a precise location and orientation in the holographic system.
