Non-invasive polarimetric apparatus and method for analyte sensing in birefringent media

A noninvasive polarimetric apparatus used to measure levels of a substance in a sample in the presence of dynamically changing sample birefringence is provided. A polarization system generates multiple states of polarized light which interact with the sample. An analyzer system receives a signal from the sample and generates a secondary signal. This signal is detected and then processed to measure levels of a substance in a sample that may be have time varying birefringent components.
