Abstract

A simultaneous 1310/1550 swept-source optical coherence tomography system is implemented by combining a novel dual-band swept laser source and an integrated common-path GRIN lensed fiber interferometer/probe. Highspeed synchronized dual-wavelength tuning is performed by using two laser cavities with a single dual-window polygonal. Simultaneous in vivo OCT imaging at 1310 and 1550 nm is demonstrated. This dual-band technique bring together common-path fiber probe potentially allows instantaneous in situ functional OCT imaging with high quality spectroscopic contrast and stable phase measurements.
