POST-PROCESSING REDUCTION OF FIXED PATTERN ARTIFACTS AND TRIGGER JITTER IN SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY

摘要

Disclosed herein are methods and systems for aligning swept-source optical coherence tomography (SS-OCT) spectral interferograms to a reference spectral interferogram based on signal information (e.g., amplitude or phase) at a fixed-pattern noise location to reduce residual fixed-pattern noise and improve the phase stability of SS-OCT systems.

主权项

1. A computer-implemented method of aligning swept-source optical coherence tomography (SS-OCT) spectral interferograms, comprising:
calculating a relative wavenumber shift between an SS-OCT interferogram and a reference SS-OCT interferogram based on signal information of the interferogram and the reference interferogram at a fixed-pattern noise location; and aligning the interferogram to the reference interferogram based on the calculated relative wavenumber shift.
