    摘要： An image pickup apparatus comprises a lens array with a plurality of lenses, a part of which lenses makes one or more stereo lens pairs; an image pickup device for taking a multifaceted compound-eye image consisting of a set of monocular images formed by the plural lenses; and a computing unit for computing range imagery from one or more pairs of the monocular images formed by said one or more stereo lens pairs. The computing unit includes imaging position determination means for determining from the monocular images an image pickup position of each of one or more subjects whose relative positional relationships with respect to the image pickup apparatus are known by dividing the multifaceted compound-eye image into the monocular images, and image distortion parameter determination means for determining an image distortion parameter based upon a determination result of the imaging position determination means.

    摘要： An optical disk apparatus for an optical disk enclosed in a disk cartridge comprises a casing for accommodating the cartridge through a cassette insertion aperture formed therein. A disk drive motor for rotating the optical disk, a loading assembly for detachably loading the cartridge on the disk drive motor, and an optical pickup device for recording data on and/or reproducing data from the optical disk are provided in the casing. Deflecting member provided for sealing the periphery of the optical pickup device against the flow of outside air introduced in the casing. A specific air-seal or door structure is provided for preventing introduction of air from the cassette insertion aperture into the casing. In the case that the optical pickup device comprises an optical head casing and an optical system accommodated in the optical head casing, the optical head casing is provided with air-supply means for supplying pressurized air into the optical head casing to maintain the interior of the optical head casing at a pressure higher than the exterior thereof.

    摘要： A disclosed optical path switching device includes a polarization bistable VCSEL that emits a beam having a rising polarization plane, a laser light source configured to emit a beam having a polarization plane orthogonal to the rising polarization plane, and an optical path switching unit configured to switch an optical path of the beam emitted from the polarization bistable VCSEL by switching the angle of the rising polarization plane of the beam emitted from the polarization bistable VCSEL. The beam emitted from the polarization bistable VCSEL is incident on an entrance window of the optical path switching unit, and the beam emitted from the laser light source is incident on an exit window of the polarization bistable VCSEL.
