Abstract
A phase-referenced Doppler optical coherence tomography (OCT) system includes a low-coherence optical radiation source and a reference source co-propagated to a sample arm and a reference arm. The low-coherence and reference optical radiation reflected from the reference and arms is detected by a pair of detectors, yielding OCT and reference interferometric data output signals. The reference interferometric data output signal can be used to correct the OCT interferometric to yield velocity-indicating images that are free from defects due to sample motion and/or interferometer jitter.
