ABSTRACT:
An optical scanner is disclosed for reading of bar code symbols on packages moving through a reading field. The scanner generates a polyphase scan pattern which is adapted for omnidirectional reading of a bar code symbol. The scanner, in one embodiment, comprises an oscillatory mirror driven by an electromechanical resonator for producing beam deflection along the amplitude axis and includes a rotary multifaceted mirror for producing beam deflection along the time axis. In another embodiment an optical galvanometer is used to produce beam deflection along the amplitude axis and in this embodiment a substantially straight line trace is produced in addition to the polyphase pattern.
