Abstract

We report on an integrated fiber optic design to implement multifiber angular compounding optical coherence tomography, which enables angular compounding for speckle reduction. A multi-facet fiber array delivers three light beams to the sample with different incident angles. Back-reflective/back-scattered signals from these channels were simultaneously detected by a three-channel spectrometer. The axial and lateral resolution was measured to be ∼3 and ∼3.5 μm, respectively, in air with ∼100 dB sensitivity. We conducted ex vivo experiments on a rat esophagus to demonstrate a contrast to noise improvement of 1.58.
