Description
We estimated the jitter of optical coherence tomography using a swept light source (SS-OCT) with methods of phase locking and Fourier transform. Phase locking could not be applied to estimating the jitter in fringe waveforms when there was a large dependence of voltage noise on time, but the dependence of jitter on local position could be estimated. We found that the Fourier transform could precisely estimate jitter even if there was a large amount of voltage noise. Jitter obtained with the Fourier transform agreed with previous results obtained through cross correlation.
