Abstract: A system for scanning human or machine readable information located on objects moving in a transport direction along a transport path. An imaging device having a first observation path and at least a 1×N sensor array is also provided. A scanning zone is located along the transport path. A rotating sweeping unit is positioned to receive light from the scanning zone and reflect it to the imaging device. The sweeping unit sweeps through the scanning zone along a sweep path. The imaging device captures a plurality of image segments that extend generally across the transport path and are each at least 1×N pixels in size. Movement of the sweeping unit is preferably synchronized to movement of the objects along the transport path.

Abstract: A presentation imaging system used for imaging machine readable information on an object is provided. The system includes a proximity sensor and an imaging device coupled to a processor. The sensor senses the presence of an object within a field of view. A light source projects a structured beam at a first intensity to define an imaging area generally co-extensive with the field of view. Upon detection of the object, the processor signals the light source to project the beam at a second, higher intensity for imaging.

Abstract: A high speed imaging apparatus for CCD based scanners comprises a housing having separate compartments which complement modular assemblies installed therein. A decoder compartment houses components associated with locating and decoding an image. An optics compartment houses the mirrors and associated optics for reflecting the subject image onto the CCD detector. A lighting compartment includes high intensity lamps and the associated components for illuminating an object to be imaged. The lighting compartment includes a heat management system which removes the heat from the high intensity lamps and prevents heat from migrating to other compartments within the housing.

Abstract: An optical scanner utilizes two linear CCD detectors and a bandpass means to improve the ability of the scanner to discriminate against specular reflection. A coded symbology is illuminated by a noncoherent light source and light reflected from the coded symbology along a first path strikes the front face of the bandpass means. The bandpass means, functioning as a notch filter, transmits a select bandwidth of light while reflecting all other light onto a first CCD detector. Simultaneously, light reflected from the bar code symbol travels along a second path, at a different angle with respect to the plane of the coded symbology than the first path, is reflected from a mirror onto the back face of the bandpass means. The bandpass means transmits the select bandwidth of light onto a second CCD detector and reflects all other light. The second CCD detector has a notch filter which permits the detection of only the select bandwidth. Since specular reflection is only experienced at a single angle, with respect to the plane of the coded symbology and each CCD detector detects an image at a different angle with respect to the plane of the coded symbology, a complete image can be reconstructed by combining information obtained from both CCD detectors.

Abstract: A focus changing apparatus for an optical scanner which increases the depth of the field of the optical scanner. The focus changing apparatus is optically located between a laser source and a scan mirror and includes a plurality of alternating curved and flat facets. Alternatively, a piezoelectric deformable mirror may be optically located between the laser source and a flat faceted scan mirror to provide for increased depth of field of the optical scanner.
