Paper Abstract

A new holographic technique has been used to make a compact, accurate and reliable POS scanner. The holo-window technology that permits compact POS scanner optical scanning horizontal plan while maintaining excellent performance in changing the scan direction, equalizing the scan velocity and collecting the signal light. The holo-window design and fabrication the HOE for such a compact POS scanner are described in this paper. Additionally, this new horizontal side scanning with very large depth of field, allows the grocery items scanned horizontally thus eliminating the commonly known carpal tunnel syndrome, hand injuries of the checkers. This newly designed POS scanner has been recognized by industry as the standard for the future POS scanning configuration.
