Paper Abstract

We present polarization-sensitive full-field optical coherence tomography (PS-FF-OCT), which is based on a bi-stable polarization switch (BSPS) device. The proposed PS-FF-OCT is a Linnik type interferometer, and allows getting both the birefringence-induced phase retardation and the intensity images of specimens with high resolutions using a pair of micro objectives and a BSPS device. Two orthogonal polarization states are formed with a regular time interval by the BSPS device that changes the polarization direction of light in a short time by switching its optic axes. Therefore, both the horizontally polarized light signal and the vertically polarized light signal from the sample can be detected with a single CCD camera. For getting a phase retardation image in real-time, the BSPS device is phase-locked with the CCD camera. The proposed method makes easy implementation of the PS- FF-OCT system without the needs of complex alignment process of using two identical CCD cameras. The experimental results confirm the feasibility of the system.
