Abstract
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.
