摘要： In an electro-optical reader, an aiming or a scanning laser has a laser chip and a monitor photodiode. Output power of a laser beam emitted by the laser is regulated by a feedback circuit for maintaining substantially constant the laser beam output power during normal operation, a disabling circuit for disabling the feedback circuit, a drive circuit for driving the chip with a drive current when the feedback circuit is disabled, and for concomitantly generating a photodiode output voltage, a current modification circuit for modifying the drive current by a predetermined current with a concomitant change in the photodiode output voltage when the feedback circuit is disabled, and a control circuit for monitoring the change in the photodiode output voltage, for determining whether the change in the photodiode output voltage is sufficient to indicate an over-power condition, and for interrupting power to the chip when the over-power condition is indicated.
