摘要： A focusing module for divergent light emitted from a source such as a laser diode. The focusing module consists of telescoping cylindrical members which focus by sliding the members along their central axis and permanently adhering the members to each other after focusing. The focusing lens is embodied in a lens assembly which prevents direct contact between the lens surface and the lens seat in one of the cylindrical members. Axial rotation between the cylindrical members, and between the base and the module is prevented by a series of notch and key elements. Consequently, the opening of the focusing module is fixed with respect to the cross-section of the light emitted, and can be shaped to match the cross section of the laser light beam thereby permitting maximum emission of focused light.

摘要： A triangulation system including a laser beam, optics focusing the laser beam on an object, a light detection unit detecting light reflected from the object due to impingement of the beam on the object, and an arrangement for determining, based on the detected light, object feature dimensions. The wavelength of the laser beam may be shorter than of infrared radiation, which allows for a reduced spot size without significant loss of depth of field. So as to reduce aberrations or a sensitivity to aberrations due to the shortened wavelength, the system may include (i) a polarization dependent coating matching the index of refraction of an element of the light detection unit to that of air for a range of angles, (ii) tilted projection optics, (iii) a prism wavefront corrector, and/or (iv) a positioning assembly, which provides for increased precision in positioning the laser diode with respect to a collimator lens.

摘要： An optical code reader is provided including imaging circuitry having an array of photo sensing devices capable of sensing light incident on the array and outputting a plurality of pixel signals corresponding to the sensed light. The reader further includes control and logic circuitry for receiving a subset of the plurality of pixel signals, processing the received subset of the plurality of pixel signals for determining if the received pixel signals meet at least one predetermined condition, and outputting a selection control signal in accordance with the processing results. A focus analysis software module executable by the control and logic circuitry determines the focus quality of the received pixel signals. A selector control software module executable by the control and logic circuitry generates a selection control signal in accordance with the determined focus quality of the received pixel signals. Selector circuitry selectively enables the imaging circuitry to output selected pixel signals of the plurality of pixel signals in accordance with the selection control signal.

摘要： A non-parallax optical auto-focusing system focuses an image and determines a distance to an optical target without being prone to errors due to parallax. The system includes a first beam splitter, a second beam splitter, and a lens positioned therebetween on an optical axis. An aiming beam is directed towards an optical target and the redirected reflected beam is received by a quadrant sensor assembly for generating an output signal indicative of a parameter of the redirected reflected aiming beam. A processor receives the output signal and generates a control signal for actuating an actuator to reposition the lens. The system continues to position the lens until the measured parameter is within a predetermined range for optimally focusing the optical target on an image sensor. The distance to the optical target is determined by using a look-up table to correlate the measured parameter to the distance to the optical target.

摘要： A miniature imager for reading target images. The optical and electrical systems of the miniature imager are optimized to reduce one or more dimensions or the volume of the imager. In accordance with one embodiment the pixel pitch and focal length are decreased for that of a larger imager to maintain a comparable field of view for each pixel. The decreased pixel pitch allows the area of the aperture and the instantaneous field of view of the pixel to remain constant while decreasing the overall size of the imager. In other embodiments apparatus and techniques reduce and/or eliminate the need for illumination of a target by the imager thereby reducing the overall power consumed by the imager and/or its overall size. The imager has an increased working range.
