    摘要: A mirror module, comprising a collection mirror comprising an opening and a first reflective surface lying in a first plane, and a fold mirror coupled to said collection mirror, said fold mirror comprising a second reflective surface lying in a second plane, the second plane not being parallel to the first plane. In addition, said fold mirror may extend behind said collection mirror at an angle, wherein said angle is established so that a laser impinging on said fold mirror is reflected through said opening in said collection mirror.

    摘要: Methods and apparatus for providing a relatively miniature scan module, for example, a small retroreflective scan engine. An exemplary scan module comprises a chassis, a drive coil, a scan motor, a laser, a mirror module and a sensor. The mirror module can comprise, in an embodiment, a single piece fold/collection mirror module. Additionally, in an embodiment, the scan motor can comprise a molded spring module.

    摘要: A multiple working range scanner includes a collection mirror which is segmented, with each segment having differing optical properties, such as focal length, optical axis, and so on. Differing segments or combinations of segments deal with reflected light received at differing working ranges, and direct it to a photodetector. In another embodiment, beam shaping may be applied to an astigmatic laser beam, for example by means of a part-concave mirror, to create an x waist in the beam which is further from the scanner than the y waist. This provides enhanced performance when the scanner is used on a bar code symbol which is not accurately aligned. In order to provide improved optical alignment within a bar code scanner, the collection mirror may be adjustable both in the x direction and in the y direction.

    摘要: Described is a scanner for reading an optical code which includes a light transmission system and an image acquisition system. The light transmission system projects light on a target. The image acquisition system receives light reflected from the target to generate an image of the target. The image acquisition system is arranged to receive the light reflected from the target at a plurality of angles so that, when specular reflection of the target is associated with a first of the plurality of angles, light from a second one of the plurality of angles is available to minimize image degradation associated with the specular reflection.
