ABSTRACT:
Laser power monitoring arrangements interrupt power to a laser used in electro-optical readers upon detection of operating conditions not conforming to preestablished standards. An auxiliary light detector independently monitors the output power of a laser beam, and directly receives a portion of the laser beam reflected from an optical assembly operative for optically modifying the laser beam.
