    摘要： An integrated optical module for an optical scanner has a lens spaced from a vertical-cavity surface-emitting laser (VCSEL) by a spacer of defined dimensions. The module, in an alternative embodiment, includes a wafer frame, a suspended mirror mounted for oscillation on the frame, a wafer substrate bonded beneath the frame and a wafer cover bonded above the frame. The cover includes a mirror travel stop to protect the mirror against shocks. A VCSEL mounted to the wafer cover produces a beam which is shaped and deflected by a diffractive optical element 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 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.

    摘要： An optical scanner such as a bar code scanner has a window comprising a holographic optical element through which both the outgoing scanning beam and the returned reflective light passes. The frequency distribution of the element may be chosen to achieve certain desirable characteristics, for example the removal of the dead zone immediately in front of the scanner and control of the beam profile and field of view. The element may be divided up into several separate zones or regions one of which is adapted to control the outgoing beam and the other of which is adapted to receive the incoming reflected light and to focus it onto a photodetector.

    摘要： An illumination time of an illumination system and/or an exposure setting of an imaging system are adjusted by a proximity system operative for detecting a product entering a field of view in a bi-optical, dual window, point-of-transaction workstation. The proximity system includes an infrared emitter for emitting infrared light to the product, and an infrared sensor for sensing return infrared light from the product. Multiple predefined thresholds are stored for the sensed return infrared light, and a predefined illumination time and/or exposure setting are stored and assigned to each predefined threshold. Adjustment of the illumination time and/or of the exposure setting is performed by comparing the sensed return infrared light from the product in real time operation with the stored predefined thresholds.

    摘要： A method and apparatus comprising an imaging system (10) with safety control for imaging target objects having a scanning arrangement (14) including a sensor assembly (22) for capturing an image from a target object. The sensor assembly (22) has a field-of-view focused by an optical arrangement (24) onto a sensor array (28). The imaging system further comprises an illumination assembly (18) having a housing (30), illumination source (38), light pipe (42), and projection lens (36). The illumination assembly (18) provides light energy toward the sensor assembly field-of-view for illuminating the target object to be imaged on the sensor array (28). The light pipe (42) comprises a multi-walled tapered body (52) having an input face (40). The walls of the body (52) create mirrored images of the illumination source (38), together with the projection lens redistribute the amount of light energy directed at the eyes of a human.

    摘要： A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for causing selected pixels in a raster pattern to be illuminated to produce an image of high resolution of VGA quality in color. The brightness of the illuminated pixels is enhanced by combining constituent laser beams of the same wavelength. The contrast of the illuminated pixels is improved by sweeping a composite beam across a polarized screen, and by making the polarizations of all the constituent laser beams of the composite beam the same.
