    Abstract: A bioptics bar code reader has first (1) and second (2) windows disposed at an angle to each other, a first imager (3) for the first window (1) and a second imager (4) for the second window (2) and first and second optics for directing light from a bar code in a reading area between the windows to the first and second imagers. The two imagers each obtain an image of the bar code in the reading area.

    Abstract: An image scanning device is provided which includes a system for determining the distance to a target to be scanned. The image scanning device includes an optical system and an image sensor array 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.

    Abstract: Actuator systems are provided for automatically focusing an optical image reader. Techniques are also provided which are applicable to the design of imaging engines and imaging lens systems associated with image readers of various types. More specifically, the present invention relates to lens guidance assemblies and actuator systems for automatically focusing an objective lens associated with an imaging system of an optical image reader. The optical image reader is preferably an optical code image reader for imaging optical codes, such as bar codes.

    Abstract: An integrated optical module for an optical scanner has a lens (24) spaced from a vertical-cavity surface-emitting laser (VCSEL) (28) by a spacer (62). The module, in an alternative embodiment, may include a wafer frame (12), a suspended mirror (14) mounted for oscillation on the frame, a wafer substrate (108) bonded beneath the frame and a wafer cover (109) bonded above the frame. The cover includes a mirror travel stop (116) to protect the mirror against shock. A VCSEL mounted to the wafer cover produces a beam which is shaped and deflected by a diffractive optical element (22,24) onto the oscillating mirror. The reflected beam passes out of the module toward an indicia to be read. Large numbers of such devices may be fabricated relatively cheaply using wafer-scale processing and assembly technology. Three large wafers (1100,1102,1104) are fabricated corresponding respectively to arrays of substrates, frames and covers. The large wafers are bonded together in a sandwich arrangement, and are then diced to produce the individual scan modules. The modules may provide either one-dimensional or two-dimensional scanning.
