Abstract

A fiber directional coupler is very often used as the interferometer for optical coherence tomography (OCT). In this paper, we present, for the first time to our knowledge, the experimental result showing influence of wavelength dependence of the fiber interferometer on the axial resolution of OCT in the wavelength region of 0.8 and 1.3/1.5μm.
