Abstract

Using data from our previously described otoscope1 that uses 1310 nm phase-sensitive spectral domain optical coherence tomography (PS-SDOCT), we demonstrate a software technique for improving the signal-to-noise (SNR). This method is a software post-processing algorithm applicable to generic PS-SDOCT data describing phase versus time at a specific depth position. By sub-sampling the time trace and shifting the phase of the subsamples to maximize their correlation, the subsamples can be coherently averaged, which increases the SNR.
