Abstract
A laser safety system providing a system for checking the presence, focus and integrity of a laser beam focusing lens is disclosed. The laser safety system checks the focusing lens properties by capturing an image of a target by viewing the target through the focusing lens from along the laser beam path. An initial, known good, image is compared to an image captured immediately before enablement of the laser beam source to determine if the focusing lens is present, focused and is not damaged. The system may also utilize a mask projected onto the target as well as a low-power visible light laser directed along the path of the processing laser to determine the focusing lens properties. The system can also provide target recognition.
