    摘要： A communication device with a time authentication requesting function uses timestamp technology to verify a device operation. When receiving an instruction for e-document scan, the communication device transmits a hash value of scanned data of an original to a TSA, and receives a timestamp from the TSA. Then, the communication device stores the scanned data assigned with the timestamp in a prescribed folder, and stores e-document scan history. When receiving an instruction for fax communication, after carrying out fax transmission, the communication device stores fax communication history. When stored history data reaches a prescribed amount, a timer time at that point of time is added to the history data, and the history data is encoded. The communication device transmits a hash value to the TSA, and receives a timestamp from the TSA. Then, the communication device stores the history data assigned with the timestamp in a prescribed folder.

    摘要： A recording and reproducing apparatus includes a light source to emit a laser beam, an information light beam irradiation unit to irradiate a medium with an information light beam, a reference light beam irradiation unit to irradiate the medium with a reference light beam so as to form a specific speckle pattern on the medium. The reference light beam irradiation unit comprises a diffusion board provided in the way of a light path through which the laser beam is passed and generating the reference light beam, a rotation controller to rotate the diffusion board, and an identification information detector to detect identification information previously formed on a surface of the diffusion board. The diffusion board comprises a plurality of encode storage regions in which different identification information is formed and a plurality of diffusion pattern generation regions specified by the identification information. A position of the diffusion board is controlled based on the detected identification information such that a desired diffusion pattern generation region comes to a position through which the laser beam is passed while the laser beam is outputted.

    摘要： A hologram recorder is provided for recording a hologram on a hologram recording medium by interference of a recording beam with a reference beam. The recorder includes a light source for outputting coherent light to be split into the recording beam and the reference beam; a spatial light modulator for modulating the recording beam into a form representing information to be recorded; an objective lens for outputting the recording beam; and a phase shift mask provided at a light entering surface of the spatial light modulator. The mask is configured to allow the recording beam to pass through, and also to partially shift the phase of the recording beam passing through the mask.

    摘要： A hologram recording and reproducing apparatus minimizes reproduction errors by servo control on the tilting of a reference beam relative to a hologram recording medium. The apparatus includes an optical detector for servo control and an optical sensor for reproduction signal conversion. A pixel pattern generator generates, on a wave surface of the recording beam, a discretely distributed recording pixel pattern corresponding to the information to be recorded, and a specifically shaped and localized servo pixel pattern for the servo control. A beam splitter splits the reflected beam from the hologram recording medium into a reproduction beam directed to the optical detector for reproduction signal conversion and a servo beam directed to the optical detector for servo control. A servo controller controls the tilting of the reference beam relative to the hologram recording medium, based on an output signal from the servo control optical detector.

    摘要： A hologram optical system includes a stem, a laser diode fixed to the stem, and a focusing error detector fixed to the stem. The focusing error detector is divided into a first region and a second region by at least one straight dividing line. The hologram optical system further includes a cap mounted on the stem so as to surround the laser diode and the focusing error detector, and a hologram mounted on the cap so as to make given positional relationship with the laser diode and the focusing error detector. When the dividing line of the focusing error detector has a positive gradient, the hologram has a distribution of interference fringes such that the product of a change rate of an X-directional component of the pitch of the interference fringes and a change rate of a Y-directional component of the pitch of the interference fringes is negative. In contrast, when the dividing line of the focusing error detector has a negative gradient, the hologram has a distribution of interference fringes such that the product of the change rate of the X-directional component and the change rate of the Y-directional component of the pitch is positive.
