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.

Abstract: The disclosure relates to systems and techniques for reading optical codes, and more particularly to code reading systems with plural imaging or scanning modules pointed in various directions toward a target volume, which increase the likelihood that a code symbol on an arbitrarily oriented object in the target volume will be read. Other aspects of the invention relate to use and configuration of hand held readers, docking devices, operator side rails, arched tunnels and mirrors for increasing the coverage of the system. Additional aspects of the invention relate to components associated with point of sale installations or code reading terminals including integrated scales, input pads, system controls and displays.

Abstract: A method of imaging a target object with an imaging reader. The method includes the following: (1) detecting light from the target object through a lens arrangement with an image sensor to generate light-field data; (2) generating a stream of image data including image data representing an expected in focus image of the target object, and (3) processing the expected in focus image of the target object to decode a barcode on the target object. The image sensor includes an array of photosensitive elements and an array of microlenses that overlays the array of photosensitive elements located at a focus plane of the microlens.

Abstract: An optical scanner such as a bar code scanner includes a segmented mirror (14), the individual sections of which have different profiles (16,18,20). By directing the scanning laser beam across the mirror, a plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.
