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 cartridge (2) contains a recording disk (4) having photosensitivity. The cartridge comprises a cartridge shell (11), a light shielding plate (12) and a shutter (13). The cartridge shell has an internal opening (18) for exposing a central portion and a recording surface of the recording disk to the outside. The light shielding plate is attached to an outer side of the cartridge shell and has an external opening (14) confronting the internal opening. The shutter is slidably disposed between the cartridge shell and the light shielding plate to open and close the internal opening. A lock mechanism locks the shutter in a closed position. For releasing the lock mechanism, it is necessary to slide a first lock member (63), which is exposed through a cavity (72), in a state that a second lock member (64) projecting into a groove (7) is pushed into the cartridge shell.

Abstract: A hologram record apparatus (100) includes a parameter set device (19), a move device (20), and a control device (18). The parameter set device (19) modifies parameters for multiple recordings such as a record angle and a focal depth in relation to at least one of signal light (L3) and reference light (L2) and can fix the parameters. The move device (20) relatively moves the focus position of the signal light and the reference light in the direction along the record surface of a hologram record medium. The control device (18) performs control so that the parameter for the last recording used for recording at the m-th focus position is used as the parameter for the first recording at the m+1-th focus position.

Abstract: A holographic storage assembly is provided which utilizes a large holographic storage media (36) disposed between two reflecting surfaces (40) and (42). An optics system (44) is disposed between the two reflecting surfaces (40) and (42) is operable to generate both a reference beam (58) and a data beam (50). The data beam (50) and reference beam (58) are generated on a virtual spot plane (100), which is then imaged from the surface of the reflecting surface (42) onto the much larger surface of the media (36). This is operable to record an interference grating at a storage location (56). During a playback operation, a reconstructed data beam (64) is generated and reflected from the surface of the mirror (40) onto a detector (68) in the deflector system (44).

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