Abstract: A confocal scanning imaging device for viewing an object includes an array of independently addressable microlasers and an array of detectors for detecting light from an object to which light from the microlasers has been directed. The array of microlasers and the array of detectors are combined into a single array, such as on a single chip, and in a pattern constructed and arranged so that different detectors are adjacent to each microlaser so that light from an illuminated object may be directed back to the vicinity of the illuminating microlaser and be detected by the adjacent detector(s). An optical arrangement directs light generated by the microlasers onto an object and directs light from an object so illuminated onto detectors adjacent to the illuminating microlaser. The optical arrangement includes a bilens and a matching lens system including two objective lenses. A microlens of pitch substantially identical to the pitch of the microlaser array collimates light generated by the microlasers.

Abstract: A fluorescence optical pickup unit (FOPU) for reading fluorescence images of biological media from solid substrates on a rotating stage. The FOPU can comprise a semiconductor laser as an excitation source, a mini-scanner to distribute the excitation light over the media, a color optical fiber as a filter, and a photodetector for detecting fluorescence. The FOPU can be miniaturized through the incorporation of a laser/detector array.

Abstract: Methods and apparatus are provided for retrieving encoded information from data tracks on an optical disk using an array of microlasers as the illumination sources, an array of micro-scale photo detectors as the detection elements, and a bilens (BL) as the main optical component. Multiple configurations are provided to position microlasers and photo detectors together on a mobile laser/detector block (LDB). Laser beams generated by the surface-emitting microlasers are guided by the BL onto the optical disk (OD) surface. The reflected light is collected by the same BL, shifted, and then directed back onto the respective photo detectors on the LDB. Illumination, detection and alignment methods and apparatus for tracking, focusing, and magnification servo controls are also incorporated on the LDB.

Abstract: Methods and apparatus are provided for retrieving encoded information from data tracks on an optical disk using an array of microlasers as the illumination sources, an array of micro-scale photo detectors as the detection elements, and a bilens (BL) or a holographic optical element (HOE) as the main optical component. Multiple configurations are provided to position microlasers and photo detectors together on a mobile laser/detector block (LDB). The microlasers and detectors may be arranged in a hexagonal lattice relationship for an optimally compact arrangement. Laser beams generated by the surface-emitting microlasers are guided by the BL onto the optical disk (OD) surface. The reflected light is collected by the same BL or HOE, shifted, and then directed back onto the respective photo detectors on the LDB. Illumination, detection and alignment methods and apparatus for tracking, focusing, and magnification servo controls are also incorporated on the LDB.

Abstract: A confocal scanning imaging device for viewing an object, includes illumination means including an array of independently addressable microlasers, detection means including an array of detectors for detecting light from an object to which light from the illumination means has been directed. The array of microlasers and the array of detectors are combined into a single array, such as on a single chip, and in a pattern constructed and arranged so that different detectors are adjacent each microlaser so that light from an illuminated object may be directed back to the vicinity of the illuminating microlaser and be detected by the adjacent detector(s). There is optical means for directing light generated by the microlasers onto an object and for directing light from an object so illuminated onto detectors adjacent the illuminating microlaser. The optical means includes a bilens and a matching lens system including two objective lenses. The system is constructed so that the relationships are as follows:.DELTA.=.

Abstract: A fluorescent imaging system provides an illuminated image of an object that has been subjected to a fluorescent dye, as well as a fluorescence image of the object. Thus, highlighted fluorescent portions of the object are viewed in context with the surrounding environment of the object being viewed. The imaging system includes an optical system which separates illumination light reflected from the object from fluorescence light radiating from the object and provides illuminated and fluorescence images of the object.
