    Abstract: 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.

    Abstract translation: 激光功率控制装置在检测到不符合预先制定的监管标准的过功率状况时，会中断电光读取器中使用的激光的电源。 在一个实施例中，在操作模式期间，将两个操作点处的激光驱动电流之间的差与在校准模式期间相同的两个操作点处的激光驱动电流之间的差异进行比较。 当在操作模式期间的差超过校准模式期间的差异预定量时，识别过功率状况。 在另一个实施例中，激光器仅被激励以在远低于监管标准的降低功率水平下发射光束，以便即使电动机驱动器失效也可以凝视。

    Abstract: Red, blue and green lasers respectively emit a plurality of red, blue and green laser beams having respective output powers. The beams are optically focused and collinearly arranged to form a composite beam which is swept by a pair of scan mirrors in a pattern of scan lines on a projection surface, each scan line having a number of pixels. A controller causes selected pixels to be illuminated, and rendered visible, by the composite beam to produce an image. A safety circuit detects a malfunction of at least one of the lasers and the scan mirrors, and deenergizes the at least one of the lasers and the scan mirrors upon detection of the malfunction.
