Doppler Optical Coherence Tomography and Turbid Polarimetrys

In most applications of biophotonics, the wave nature of light is ignored, and the light field is modelled as a stream of neutral particles.
However, when polarization properties and/or interference effects form the basis of a given optical interrogation method, the wave nature of light must be considered. In this talk, I shall present the underlying physics and the biomedical applications of two particular wave-based optical techniques under development at the Toronto Biophotonics Laboratory -- turbid polarimetry and optical coherence tomography. For the former, applications to glucose monitoring and tissue structural birefringence assessment will be emphasized. For the latter, the extension to microvascular blood flow monitoring (via the Doppler effect) and uses in the context of dynamic treatment feedback will be described.
