    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： 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 lensholder holds at least one fixed optical lens and a variable focusing element in a spaced relation along an optical path through which light passes in an electro-optical reader. The variable focusing element has a pair of electrodes across which a voltage is applied to optically modify the light passing through the fixed optical lens and the variable focusing element. The lensholder directly electrically conductively contacts the electrodes and establishes an electrically conductive path between each electrode and an exterior of the lensholder.

    摘要： A method and apparatus are provided for controlling the operation of a Laser Projection Display (LPD). Generally, the LPD is comprised of a laser, an optical system and a controller. The laser is adapted to emit a beam of laser light. The optical system is adapted to scan the beam of laser light on a display surface in a two-dimensional raster pattern. The controller is adapted to control the rate at which the laser beam is scanned to produce regions of varying resolution on the display surface. The controller is also adapted to present laser light onto the display surface within only selected portions of the two-dimensional raster scan pattern so that spaced apart image regions may be created.
