Abstract

We report the first (to the best of out knowledge) en face polarization sensitive optical coherence tomography (PSOCT) system. The transverse raster scanning of the target is achieved using a pair of galvo-scanner mirrors. The setup is based on incoherent detection in two optical and electronic channels and employs balanced detection to reduce the excess photon noise generated by the low coherence source (superluminescent diode). The outputs of the two channels are processed using software to provide a polarisation insensitive (pure reflectivity) image and a birefringence retardation map. Images from ex vivo (human tooth) and in vivo targets (human retina) have been acquired. Particulars of en face optical coherence tomography imaging of birefringent tissue are discussed.
