Optimization of an angled fiber probe for common-path optical coherence tomography

摘要

We studied optimization of common-path optical coherence tomography (CP OCT) sensitivity through angled fiber probe. The magnitude of reference power derived from the tip of the fiber was optimized through careful selection of the polishing angle. We experimentally measured the signal-to-noise ratio at different polishing angles to validate the effectiveness of this technique. We also obtained OCT images with the reference optimized CP OCT with more than 10 dB improvement in SNR..
