Abstract:
1. A method of non-invasive analysis of a target, said method comprising: generating probe radiation and multiple reference radiation that have orthogonal polarization characteristics; modifying at least some of said polarization characteristics, wherein the step of modifying polarization characteristics further includes the step of rotating components of the multiple reference radiation, with the exception of the DC component, such that the co-propagating radiation contains a minimized amount of DC component of reference radiation, said DC component of reference radiation thereby forming an optimized amount of a reference radiation component; capturing at least part of said probe radiation scattered from within said target to form signal radiation; combining said signal radiation and at least some of said reference radiation to form co-propagating radiation, wherein said co-propagating radiation is composed of maximized signal radiation and optimized amounts of at least one component of the multiple reference radiation components; detecting at least one interferometric signal generated by at least part of said copropagating radiation to form an electronic signal; and processing said electronic signal to achieve non-invasive analysis of said target.
