BAR CODE SYMBOL SCANNING SYSTEM FOR AUTOMATICALLY LASER SCANNING BAR CODE SYMBOLS WITHIN A 3-D SCANNING VOLUME AND PRODUCING INFORMATION SPECIFYING THE POSITION OF EACH BAR CODE SYMBOL DETECTED WITHIN SAID 3-D SCANNING VOLUME

摘要

A holographic laser scanners of ultra-compact design capable of reading bar and other types of graphrical indicia within a large scanning volume using holographic optical elements and visible laser diodes, and also a method of designing and operating the same for use in diverse applications.
