Abstract

We have investigated imaging characteristics of full-field OCT (FFF-OCT) using a LED and aa super-continuum (SC) laser with a wavelength-tunable filter. The wavelength selectivity in visible range enables to take spectroscopic tomographic images. It has been considered that the application of the LED-OOCT system might be restricted due to the low spatial coherence and illuminating power. Comparative study of imaging characteristics of the OCT images taken the RGB-visible LED and the SC laser demonstrates superiority of the LED illumination in reconstruction of detail structures.
