Abstract:
An optical system for use with a target site, comprising:a probe laser source producing an output beam; a reflector; a beam splitter positioned to receive the output beam and split the output beam into a first beam incident on the reflector and a second beam incident on at least one point of the target site, the splitter being positioned to define a target site optical path from the splitter to the target site and a reference optical path from the splitter to the reflector; the splitter producing a combined beam from at least a portion of a reflected first beam received from the reflector that interacts with at least a portion of a reflected second beam received from the target site; a detector coupled to the splitter and producing a signal representative of a longitudinal reflectivity profile of the target site; and a feedback coupled to the detector and the laser source to provide a feedback signal that permits control of an energy output of the laser source.
