ABSTRACT:
An optical scanner comprises a scanner housing including a scan window, a laser light source, reflected light detector and a Micro-Electro-Mechanical Systems (MEMS) mirror array arranged to produce a scan line pattern. The light from the laser source is adjustably focused by the MEMS mirror array so as to enable auto-focusing of the laser light during the scanning of a bar code.
