摘要： Laser power control arrangements interrupt power to a laser used in electro-optical readers upon detection of an over-power condition not conforming to preestablished regulatory standards. In one embodiment, during an operational mode, a difference between laser drive currents at two operating points is compared to a difference between laser drive currents at the same two operating points during a calibration mode. The over-power condition is recognized when the difference during the operational mode exceeds the difference during the calibration mode by a predetermined amount. In another embodiment, the laser is only energized to emit the beam at a reduced power level well below regulatory standards for staring at even if a motor drive failed.

摘要： Crosstalk between a drive coil and a feedback coil is eliminated by a motor drive circuit operative for generating the drive coil as a square wave, and by removing the crosstalk which occurs at zero transitions of a feedback signal. The drive coil is used to oscillate a scan mirror employed in an image projection arrangement or an electro-optical reader.
