Abstract

This study describes a phase-shifting method based on orthogonal polarized light by using complex Fourier domain optical coherence tomography (FD-OCT) to increase the speed of image scanning and to resist vibration and other environmental disturbances. Two FD-OCT interferograms corresponding to orthogonal polarization components can be obtained simultaneously. After using a π/2 phase-shifting algorithm, removing unwanted components becomes possible, including dc and autocorrelation terms, from the interferogram. This method doubles the measurement range. In other words, this approach enables one-shot and full-range FD-OCT. Experimental results show that the reconstruction parameters of the sample are close to the conventional time-domain optical coherence tomography.
