Experimental Investigation into High Speed FD-OCT Imaging Based on Orthogonally Polarized Light

Abstract:

A phase shifting method based on orthogonal polarized light is proposed over complex Fourier domain optical coherence tomography (FD-OCT) to enhance the speed of OCT image scanning and to resist the environmental disturbance such as vibration. In the proposed approach, one simple wave plates (a quarter-wave plate ) are inserted into the system with appropriate rotational angles, the one interference data on orthogonal polarized directions will then manipulate with π/2 phase-shifting algorithm to reduce the scanning frequency. In other words, the proposed approach enables one-shot and full-range FD-OCT.
