ABSTRACT:
A method and apparatus is provided for reading two-dimensional patterns, such as matrix symbols or signatures, using moving beam laser scanners to take advantage of the large depth of field inherent in laser scanners. A pixel generating element and a tracking element together create a digitized image of a target symbol by scanning a laser beam across the symbol. As the pixel generating element generates pixel data composing the digitized image, the tracking element tracks the position of the laser beam in the scanning pattern, and generates laser position data indicating the instantaneous position of the laser associated with particular pixels. The laser position data is then stored in a data memory in association with the generated pixel data, and a microprocessor utilizes the stored pixel data and laser position data to create an image of the target symbol.
