Abstract: An electro-optical, retroreflective scanning module has a base, a first circuit board, and a second circuit board mounted orthogonal to the first circuit board. The base supports a light emitter for producing a scanning beam. The beam reflects off a generally planar scan mirror affixed to a stationary concave collection mirror, to a reflector mounted on a drive for oscillation. A detector included in the module senses light reflected from an indicia scanned by the beam. The reflected light is reflected off the reflector and directed to the collection mirror before reaching the detector. The beam and the field of view of the detector are simultaneously scanned.

Abstract: Laser power control arrangements interrupt power to a laser used in electro-optical readers upon detection of operating conditions not conforming to preestablished standards, and adjust power to the laser to enhance reader performance without violating prevalent safety standards.
