In Vivo OCT Imaging Using Wavelength-Swept Fiber Laser Based on Dispersion Tuning

We are developing a wide wavelength-swept fiber laser based on a dispersion tuning method for application to swept-source optical coherence tomography (SS-OCT) imaging. The tuning range of the laser is about 140 nm and the output power is 8 mW on average. We successfully obtained the in vivo OCT picture of the human skin at 1-kHz sweep rate.
