Abstract

We demonstrate micron-class-resolution frequency-domain OCT at high acquisition-speeds using a commercial supercontinuum source (i.e. 300nm bandwidth centered at 800nm) and a broadband custom astigmatism-corrected spectrometer (i.e. < 0.1 nm spectral resolution over 400nm bandwidth). We achieved 1.3 μm axial resolution in, in vivo skin tissue, with an acquisition speed of 23 A-scans per sec using the implemented FD-OCT.
