Abstract
A method, apparatus and system for optimizing the magnitude of reference levels in non-invasive imaging and analysis is disclosed. Optimizing the magnitude of reference levels enables improving signal to noise ratios and thereby improving the sensitivity and performance of the imaging and analysis system. The invention includes dynamically modifying the magnitude of one or more reference beams and significantly reducing the magnitude of undesirable reference radiation components. It may further include one or more stabilizing feedback systems.
