Design of a Multiple-reference Time-domain Optical Coherence Tomography System

Optical coherence tomography (OCT) is a non-invasive, three-dimensional imaging technique that offers close-to-histology-level image quality [1]. In conventional timedomain (TD)-OCT systems depth scanning is achieved by modifying the relative optical path length difference of the reference and the sample arms in a sequential way using mechanical scanners. Due to the moving reference mirror TD-OCT systems require an inherently long acquisition time. To overcome this problem non-moving part solutions have been proposed such however, each solution has its own drawbacks [2-4].
