Methods and systems for performing angle-resolved fourier-domain optical coherence tomography

摘要

Angle-resolved Fourier-domain optical coherence tomography for measuring spatially-resolved angular backscattering distributions from transparent and turbid samples is presented. Speckle reduction and generating image contrast are shown. A wavevelength-swept laser source and line-scan camera are used. The input beam on the sample to be measured is collimated, with the reference beam being spatially expanded. The backscattered light from the sample interferes with the spatially expanded reference beam.
