Abstract
We describe high-speed Fourier domain optical coherence tomography (OCT) using optical demultiplexers (ODs) for spectral dispersion. The OD enables separation of a narrow spectral band of from a broadband incident light at 256 different frequencies in intervals centered at . OCT imaging of 60,000,000 axial scans per second was achieved through parallel signal acquisition using 256 balanced photoreceivers to simultaneously detect all the output signals from the ODs in a Fourier domain OCT system. OCT imaging at a frame rate, 1100 A-lines per frame, depth range, and resolution was demonstrated using a resonant scanner for lateral scanning.
