Abstract

In this study, we demonstrated an 800-nm Fourier-domain/swept-source optical coherence tomography (FD/SS-OCT) for ophthalmology. A swept-source was constructed with a semiconductor optical amplifier, a Fabry-Perot tunable filter, and a 1×2 fiber coupler. The swept source produced laser output with a tuning range of 42 nm, an averaged optical power of 3.9 mW, and a tuning speed of 2.0 kHz with bidirectional wavelength-swept. FD/SS-OCT has an axial resolution of 10.4 μm in air and a sensitivity of 89.7 dB. We obtained in vivo retinal OCT image of a healthy volunteer with 1,000 A-lines/frame and an acquisition speed of 2.0 fps.
