Abstract

A versatile system and method for VCSEL (vertical cavity surface emitting laser) bar code and data scanning is disclosed, including a housing (102) having a scanning surface (116), a detector element (106) disposed within the housing in close proximity and normal to the scanning surface, VCSEL component (104) disposed within the housing in close proximity to the detector element and scanning surface, and an aperture (122) formed within the housing between the scanning surface and the detector element.

Description

technical field [0001] The present invention relates generally to data encoding, and more particularly to a general system for vertical cavity surface emitting laser (VCSEL) based bar code reading and scanning. Background technique [0002] In order to transfer data and information conveniently and efficiently, bar code scanning is used in a large number of commercial and industrial applications. As the requirement to quickly process large amounts of information increases, efforts have been made to improve the efficiency and effectiveness of barcode scanning. In general, the amount and efficiency with which a particular barcode can convey information is constrained by the minimum required width (ie, spacing) of the individual bars in the barcode. As the minimum required stripe width decreases (ie, a smaller pitch is achieved), more stripes can be programmed in a given space. Thus, bar coding with smaller pitches increases the amount of data that can be encoded in a given s...
