Paper Abstract

Optical coherence tomography (OCT) system based on optical frequency-domain reflectometry (OFDR) has been developed using a superstructure-grating distributed Bragg reflector (SSG-DBR) laser, which can tune the wavelength from 1533 to 1574 nm stepwise with tuning speed of 10micro s per 0.1 nm step. Theoretical expressions of OCT imaging by the discretely swept OFDR-OCT system are described. OFDR-OCT images are demonstrated for a few biological tissues; an extracted canine, human skin, human nail, and anterior segment of enucleated porcine eye.
