摘要： An actuator for an objective lens in an optical head which provides a compact structure that does not move the laser beam relative to the objective lens in the tracking mode. The low profile optical head design is accomplished by designing the optical beam path in the same space occupied by the tracking and focusing motor. A mirror reflects a laser beam from a laser at an angle to an objective lens. The objective lens and the mirror are coupled together in a manner allowing movement of the objective lens relative to the mirror along the path of a laser beam from the mirror to the objective lens. The objective lens, mirror and the coupling mechanism are all moved along the path of the laser beam between laser and the mirror for tracking control. Because the mirror moves with the objective lens, there is no beam clipping or beam distortion. For focusing, the objective lens is moved relative to the mirror. The laser, the detector and their associated optics are stationary, with only the mirror and objective lens being moved, thus limiting the mass moved and the power requirements. The simple structure eliminates the need for a fiber optic cable.

摘要： An improvement to the above described techniques for producing a holographic stereogram. The present invention uses a hologram lens in the process of creating the holographic stereogram, and also uses Fourier transforms of the images for projection onto the recording medium, not the images themselves. A lens between the generated images and the recording medium performs the inverse Fourier transform to convert the image back into a normal image.

摘要： An optical head which uses a single diffraction grating to eliminate the need for both a beam-splitter and a biprism lens. This invention allows the placement of all the elements except the photodetector along a single optical axis with the photodetector immediately adjacent to the optical axis. This arrangement reduces alignment problems and vibrational errors. A semiconductor laser is provided which produces a laser beam which impinges upon a movable objective lens. The objective lens focuses the laser beam onto an information medium. A holographic diffraction grating is placed between the laser and the objective lens. The diffracted beams on the forward path from the laser to the objective lens are not used, but on the return path, one of the diffracted beams is focused onto a photodetector. In a first embodiment, the photodetector is adjacent the semiconductor laser in substantially the same plane. In a second embodiment, an additional lens is used to produce an additional focus point intermediate the laser and the medium, with the photodetector being in substantially the same plane as this additional focal point. By using an appropriate fringe pattern for the hologram lens, the return beam can be focused on the photodetector as desired.

摘要： An optical sensor consisting of a nearly monochromatic point source such as a light emitting diode (LED) or a vertical cavity surface emitting laser (VCSEL) which is mounted on a multiple element detector. When this sensor is placed near a moving object with a reflective periodic pattern on its surface (such as an optical disk), it can produce a signal which can be used to control the position of the object. Unlike other sensors which often use lenses to project the light emitted by the light source onto the object and collect the light reflected from the object and project them onto a photodector, this new sensor performs the tasks of object illumination and light collection without the use of any optical component. A self-imaging principle is used by placing the detector on the self-imaging plare of the object to detect the motion of the object. In order to detect the periodic signal in the self-image of the periodic object, the detector element is covered with a grating structure having the same period or two times the period of the object.

摘要： An improved optical head for reading information recorded on a reflected medium. The optical head uses a hologram lens assembly having a transparent plate and a hologram lens, the transparent plate being obliquely positioned relative to a forward and a return beam paths. The transparent plate corrects beam aberrations in a laser beam emitted by a semiconductor laser on the forward beam path. The hologram lens diffracts the laser beam on the return beam path onto a photodetector. Both the transparent plate and the hologram lens add beam aberrations to the defracted laser beam on the return beam path for tracking purposes. The hologram lens assembly may also include a second hologram lens, preferably a three beam diffraction grating, for tracking purposes. The hologram lens and the diffraction grating may be located on the obliquely positioned transparent plate or on other transparent plates.

摘要： A semiconductor laser assembly is provided with a photodetector module and a laser module mounted on orthogonal surfaces of a heatsink. The photodetector module includes a photodetector and two electrically isolated wire bond blocks, each with two surfaces parallel to the orthogonal surfaces of the heatsink. The laser module includes a laser diode bonded and a wire bond region with two surfaces also parallel to the orthogonal surfaces of the heatsink. Both of the wire bond block surfaces of the photodetector modules are thus parallel to the wire bond region surfaces on the laser module, allowing wire connections to be made between parallel surfaces before the heat sink is mounted on a header. One of the surfaces of each of the wire bond blocks and regions is parallel to the pins of a header, allowing attachment of wires from the photodetector module and the laser module to the pins without rotating the header and pins.
