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 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 image scanning device (12) is provided which includes a system (404, 604) for determining the distance (Zo) to a target to be scanned. The image scanning device includes an optical system and an image sensor array (403, 603) for focusing a light beam and imaging the target. The device preferably includes an automatic focusing system for adjusting the position of the optical system in order to adjust the focal point, and thereby focus the image of the target onto the image sensor array. In one embodiment of the image scanning device, the distance is determined by analyzing a collimated aiming pattern formed by collimating the light beam. In another embodiment, the distance is determined by analyzing a speckle pattern caused by the speckle effect upon the light beam hitting the target.
