Enhancement Of Optical Coherence Tomography Axial Resolution By Spectral Shaping
CHINESE PHYSICS LETTERS(2002)
Abstract
We propose a new method of changing the spectrum shape to improve the axial resolution of optical coherence tomography (OCT). Theoretical analysis shows that certain spectral shaping can shorten the coherence length. Comparisons of the simulation and experimental measurements of spectral shape and axial resolution of OCT are given, showing that the axial resolution of OCT is enhanced by a factor of 1.4.
