Laser Projection System

摘要

A laser projection system having built-in safety systems is disclosed. Further disclosed is a method of operating a laser projection system such that safe operation is a factor only of meeting a threshold distance between the laser unit and an audience member. To accomplish safe operation at the threshold distance, the laser projection system is pre-calibrated to operate below maximum permitted exposure levels at the threshold distance. In this manner of operation, laser lighting can be accomplished by non-laser professionals without the complexity, external sensors, and need for calibration at the venue.

主权项

1. A system for projecting a laser onto an audience, comprising:
a laser source; a monitoring system,
wherein the monitoring system observes a plurality of output parameters of the laser source;wherein the monitoring system generates an output signal; a calibration interface, wherein the plurality of output parameters of the laser source are calibrated such that a laser beam emitted from the laser source does not to exceed a threshold exposure level at a given distance; a safety system that receives the output signal, wherein the safety system attenuates the laser beam in the event the laser beam exceeds the threshold exposure level.
