Abstract
We present a polarization sensitive spectral domain optical coherence tomography system that is capable to retrieve with a single camera both retardation and optical axis orientation. The method is based on a differentiation between orthogonal polarization channels through spatial modulation introduced by an electro-optic modulator. Proof-of principle using a chromatic quarter wave plate designed for 1300nm as a sample and acquisitions of a piece of borealis, a highly birefringend plastic is provided. Results of the method for in-vivo imaging of a fingertip are presented.
