Patent number: 8004950Abstract: An optical pickup for recording a hologram by using an angle multiplexing method. An optical beam is separated into two beams, a signal beam and a reference beam having different convergence/divergence degrees, by using an optical component such as a diffraction lens. The signal and reference beams are made incident upon the same objective, and the optical component or the objective lens is moved in a direction perpendicular to an optical axis, to thereby realize angle multiplex recording. If an optical information recording medium is inclined, the optical component or the objective lens is moved along the direction along which the optical information recording medium moved to change an angle of the reference beam incident upon the optical information recording medium and compensate for degradation of a reproduction signal.Type: GrantFiled: February 27, 2008Date of Patent: August 23, 2011Assignees: Hitachi, Ltd., InPhase Technologies Inc.Inventors: Tatsuro Ide, Kenichi Shimada, Masahiko Takahashi, Takeshi Shimano, Kevin R.

Patent number: 7990830Abstract: In holographic recording, it is important to form stably an interference fringe between a reference beam and a signal beam in a holographic storage medium. To suppress factors degrading stability of the interference fringe, such as fluctuation of atmospheric air, position displacement of optical components and the like during propagation of the reference and signal beams, an optical pickup and an optical information recording/reproducing apparatus adopt an optical system structure providing a higher proportion of optical components shared by the reference and signal beams optical path than conventional optical system structure. To increase the proportion of shared optical components, the signal beam and the reference beam pass through the PBS prism as parallel beams and a concave lens is placed on a reference beam path just before the objective lens.Type: GrantFiled: February 27, 2008Date of Patent: August 2, 2011Assignees: Hitachi, Ltd., InPhase Technologies Inc.Inventors: Kenichi Shimada, Tatsuro Ide, Kevin R.

Patent number: 7813017Abstract: A method and system is disclosed for increasing the holographic storage capacity of a holographic recording medium using an irradiance-tailoring (e.g., optical) element by changing the irradiance profile of the modulated object beam (e.g., by imparting motion to an irradiance-tailoring element and/or the holographic recording medium and/or by reconfiguring (e.g., periodically) the phase profile of a stationary irradiance-tailoring (e.g., optical) element) to minimize the effects of fixed-pattern noise buildup from occurring in the holographic recording medium.Type: GrantFiled: December 29, 2005Date of Patent: October 12, 2010Assignee: InPhase Technologies, Inc.Inventors: Benjamin C. Ihas, Samuel Paul Weaver, Ken E. Anderson, Aaron Wegner

Patent number: 7548358Abstract: Methods and systems are provided for obtaining a phase conjugate reconstruction beam for use in retrieving holographic information from a holographic storage medium. These methods and systems include generating a coherent light beam that is a reproduction of the reference beam used in storing the holographic information in the storage medium. This coherent light beam is then directed through the holographic storage medium at the same angle and location of the reference beam during recording of the hologram. The directed coherent beam is then reflected back through the storage medium so that the reflected coherent light beam provides a phase conjugate of the reference beam and passes through the storage medium at the same angle and location that the reference beam passed through the storage medium during recordation of the hologram.Type: GrantFiled: May 25, 2006Date of Patent: June 16, 2009Assignee: Inphase Technologies, Inc.Inventors: Brian Riley, Ken E.
