Multi-System Laser Safety Shutter Controller.

摘要

The use of lasers in research laboratories has become commonplace. With this increased use of lasers comes the inherent danger from laser radiation to the user. While burns are thought of as the primary danger from lasers, a more immediate hazard is the loss of eye sight. This danger increases in laboratory environments where it is impractical to completely enclose the beam path. To provide an increased level of safety for these instances, a laser safety shutter controller has been designed and implemented. This system provides and effective interface between the laboratory entrances and accompanying safety shutters to provide laser beam blockage during a laboratory breach. In addition, this system provides a host of convenience features that allow the laser user to easily control laser emission. These features include shutter and interlock control of up to eight independent lasers, push button shutter control and infrared remote control. (rh)
