We present a phase fluctuation calibration method for polarization- sensitive swept-source opticalcoherence tomography (PS-SS-OCT) using continuouspolarization modulation. The method uses a low-voltagebroadband polarization modulator driven by a synchronizedsinusoidal burst waveform rather than anasynchronous waveform, together with the removal of theglobal phases of the measured Jones matrices by the useof matrix normalization. This makes it possible to averagethe measured Jones matrices to remove the artifact due tothe speckle noise of the signal in the sample without introducingauxiliary optical components into the sample arm.This method was validated on measurements of an equinetendon sample by the PS-SS-OCT system.
