Abstract:
Scanners, methods, and computer storage media having computer-executable instructions embodied thereon that process variable sized objects with high package pitch on a moving conveyor belt are provided. The scanners include a substrate and a plurality of sensors attached to the substrate. The plurality of sensors form an array of sensors having at least two or more rows of off-axis sensors. The sensors may include a one or more area array sensors. The arrays of sensors captures moving objects row by row and are optimized reduce object spacing on the conveyor belt. Additionally, the scanner having the array of sensor may process different objects having different heights at the same time. Accordingly, object throughput on the conveyor belt is increased by reducing minimum object gap (e.g., processing of "no gap" or non-singulated objects).
Abstract:
The invention relates to an illumination device for the strip-wise illumination of a flat article (BN). The inventive illumination device comprises a mirror system that is disposed symmetrically to an optical axis (OA) with respect to its diameter and that consists of a plurality of directly subsequent mirror segments (S1, S21, S22, S3). The inventive design of the mirror system in the form of mirror segments prevents undesired interferences through reflections and scattered light from being produced. It further reduces the dependence of the light intensity in the object plane of the distance of the article and allows a more compact design of the entire system.
Abstract:
A hand-held scanner comprises contact image scanning technology. A waveguide (2) formed in a substrate is comprised of an elongate light pipe (5) which includes a reflective layer (7) deposited on an inside lateral surface. Light sources (6) disposed at each end of the light pipe emit rays of light through the light pipe (5). The rays of light propagate in the light pipe (5) until striking an area of a reflective surface (7). The reflective surface directs the rays away from the lateral surface and onto the scan line of a document (3). The light of the illuminated scan line is reflected back through the waveguide, through a slit (10) not covered by the reflective layer (7), and onto an optical lens array (8) which focuses the light onto an optical sensor array (11) that converts the image into a digital image to be saved in an internal memory. In a further embodiment (Fig. 4), the waveguide (2) includes a mirrored surface (12) that directs the light of the illuminated scan line through the waveguide (2) and through the optical lens array (8).
Abstract:
An arrangement for use with a document scanner for eliminating overlap of images in a multi-camera system. The degree of overlap is determined utilizing data obtained from scanning a substrate having a slanted line (91) thereon. Means (87) are provided for suppressing any resulting double images.
