Abstract
By use of supercontinuum source, which emits bright, and ultrawideband beam, we can demonstrate ultrahigh resolution (UHR) OCT which enables us to achieve highly sensitive and precise imaging. We demonstrated UHR-OCT imaging of several different samples using supercontinuum at 5 different wavelengths among 0.8 – 1.7 um wavelengths. In this review paper, we introduce the advance of UHR-OCT based on our recent achievement.
