Abstract
Official abstract text for this publication.
Method of and system for reading bar code symbols using a hand-supportable laser scanning bar code symbol reading system supporting an improved level control over the length and intensity characteristics of laser scan lines projected onto scanned objects, at any instant in time, in a manner dependent the detected location, distance or range of the scanned object in the scanning field of the system during system operation. The system includes a laser scanning module that projects the laser scanning beam through a light transmission window, and across a laser scanning field in which an object is located, while the laser scanning beam is blanked out during the laser scanning cycle according to a laser source blanking function that is determined by the estimated distance, or data representative thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for reading code symbols in a scanning field, comprising: a source for generating a light beam; and a scanning mechanism for scanning the light beam at a sweep angle across the scanning field and along a scan line during a scanning cycle; a drive circuit for supplying current to the scanning mechanism to achieve the sweep angle; a photo-detector for detecting the intensity of light reflected from the scanning field and generating a first…
