摘要： A laser projection system having personnel protection utilizes a proximity detector system to detect any approach by an operator or other personnel within a predetermined protection zone. If an approach by personnel is detected within a predetermined zone, the laser output is either interrupted or reduced to a safe level, e.g., such as less than 5 mW, or to a level defined as safe for the detected approach distance. Alternatively, the proximity detector system can also utilize an array of highly directional proximity detectors, infrared detectors, and/or incorporation of a detection mechanism onto the laser projection system frame itself. An electronic circuit directly modifies the output power of the laser projector to an approved level based on feedback of the speed of the scanned beam and the detected closest approach distance.

摘要： A multiple laser head projector includes a sensor that senses the presence or absence of a laser beam from a first of the laser heads and signals a switching device to switch to a second laser head when a laser beam is not detected by the sensor from the first laser head. Thus, the multiple laser head projector may be utilized to provide continuous operation of the multiple head laser projector when one of the lasers fails. The multiple head laser projector may also be utilized for diagnostic testing of the laser heads, such as during start-up. Further, the multiple head laser projector may be utilized to signal the power output of the laser heads and thus the expected remaining life of the laser heads.
