Abstract
A method, apparatus and system for non-invasive imagining and analysis involves generating probe radiation and reference radiation that have orthogonal polarization characteristics and controlling the polarization characteristics such that substantially all the back scattered probe radiation co-propagates with controlled amounts of components of the reference radiation, thereby improving signal to noise ratios and hence performance of imaging and analysis systems. A preferred embodiment of the invention includes a rotational sensitive mirror that systematically rotates the polarization vector of higher order components of the reference radiation.
