Abstract
The present invention is directed toward a monitoring and control system for an optical system. In one aspect of the present invention the system may include an interferometer that splits an input beam into a transmitted portion and a reflected portion. The interferometer introduces a path length difference between at least a segment of the transmitted and reflected portions that recombine to form an output beam having an intensity that varies as a function of wavelength of the input beam.
