Claim:
1. Optical polarization shift measuring system comprising: (A) a monochromatic optical source having a first linear polarizer; (B) substantially illuminated by the source, a sample stage capable of temporarily immobilizing a living sample; (C) proximate to the sample stage and within a predetermined angular range with respect to the source illumination of the sample, a narrow-band optical detector capable of detecting polarization angles from the illuminated sample; and (D) in conjunction with the source and the detector, a linear polarization angle comparator for comparing polarization of the source with a polarization maxima region measured by the detector; wherein the linear polarization angle comparator includes an electronic block having at least one item selected from the list: a synchronizer, a statistical data collector, a statistical data analyzer, and a statistical data processor; wherein the polarization maxima region is substantially a zero-signal crossing; and wherein the statistical data collector, the statistical data analyzer, and the statistical data processor are configured to collect, aggregate, and average measured data.
