摘要： Methods and systems for performing dynamic aperture holography are described. Examples include a method of recording multiple holograms in a photosensitive recording medium, where multiple signal beam angular apertures used to record the multiple holograms differ from each other. The multiple signal beam angular apertures can facilitate using a larger range of reference beam angular apertures. The multiple holograms are typically multiplexed, and examples of dynamic aperture holography enable packing the multiplexed holograms more densely in the recording medium. Some dynamic aperture holography systems include monocular objective lens architecture.

摘要： An optical disk information device includes a laser light source that emits a luminous flux with a wavelength λ, an objective lens having a numerical aperture NA, a splitting element, a photodetector, a central portion amplifier, at least two end portion amplifiers, an adder, a control signal processing section having a tracking switcher that inverts a polarity of a tracking control signal depending on whether a track scanned by a condensing spot corresponds to a land portion or a groove portion, and a gain controller that, when the polarity of the tracking control signal is inverted, switches gains of the central portion amplifier and the end portion amplifiers and sets the gain of the central portion amplifier substantially lower than the gain of at least one of the end portion amplifiers so as to reduce crosstalk from adjacent tracks in the optical disk.

摘要： In correspondence to a hologram element of a hologram unit, on a light-path between the hologram element and an optical recording medium, a light blocking aperture for blocking, of a laser beam emitted from a light source, unnecessary lights other than an application light applied from the light source to an information recording surface of the optical recording medium and a reflection light reflected by the information recording surface of the optical recording medium and received by a light receiving element is formed. The light blocking aperture is provided with an unnecessary light guiding surface for guiding the unnecessary lights other than the application light and the reflection light in a direction other than a direction of the light receiving element. The unnecessary lights other than the application light and the reflection light can be securely prevented from entering into the light receiving element, and signals can be stably detected.

摘要： A device for writing optical information including a roof mirror array, a lens array, an optical-path separator, a mirror member, a housing, and a self-scanned recording element. The roof mirror array, the lens array, the optical-path separator, and the mirror member are retained by the housing in a prescribed mutual positional relationship. The housing has a pair of slits, one of which is covered with the light-signal producing surface of the self-scanned recording element. The housing is shaped such that the light-signal producing surface of the self-scanned recording element is held in registration with an object surface on which an unmagnified object image would be formed by the lens array and the roof mirror array.
