Abstract
Various systems and methods of monitoring laser safety by sensing contact of the system with a sample are provided. The system includes a focusing element for focusing an incident light from a laser light source onto a sample, an optical element having a collection zone for collecting a signal from the sample, a reflected light sensor for sensing a reflected light from the sample, wherein the reflected light sensor is located outside the collection zone of the optical element and on an inner surface of a housing of the system, an electrical circuit operably connected to the reflected light sensor and the laser light source and configured to control power to the laser light source in accordance with the reflected light sensed by the reflected light sensor and a spectral analyzer for processing the signal. Methods and other systems are also described and illustrated.
