Angular high-speed massively parallel detection spectral-domain optical coherence tomography for speckle reduction
Author(s): Yuuki Watanabe; Haruyuki Hasegawa; Seiya Maeno

Paper Abstract

We demonstrate speckle reduction based on angular compounding using parallel-detection spectral-domain optical coherence tomography (OCT). An ultrahigh-speed two-dimensional complementary metal-oxide semiconductor camera acquired angular and spectral interference fringes (128×1024 pixels) simultaneously at 15,000 frames/s for a single lateral point. A signal-to-noise ratio improvement of 8 dB was achieved for imaging human skin in vivo by averaging 121 angle-resolved OCT images.
