High resolution Fourier domain optical coherence tomography in the 2µm wavelength range using a broadband supercontinuum source
High resolution Fourier domain optical coherence tomography in the 2µm wavelength range using a broadband supercontinuum source
A 220nm bandwidth supercontinuum source in the two-micron wavelength range has been developed for use in a Fourier domain optical coherence tomography (FDOCT) system. This long wavelength source serves to enhance probing depth in highly scattering material with low water content. We present results confirming improved penetration depth in high opacity paint samples while achieving the high axial resolution needed to resolve individual paint layers. This is the first FDOCT developed in the 2µm wavelength regime that allows fast, efficient capturing of 3D image cubes at a high axial resolution of 13µm in air (or 9µm in paint).

Abstract
A 220nm bandwidth supercontinuum source in the two-micron wavelength range has been developed for use in a Fourier domain optical coherence tomography (FDOCT) system. This long wavelength source serves to enhance probing depth in highly scattering material with low water content. We present results confirming improved penetration depth in high opacity paint samples while achieving the high axial resolution needed to resolve individual paint layers. This is the first FDOCT developed in the 2µm wavelength regime that allows fast, efficient capturing of 3D image cubes at a high axial resolution of 13µm in air (or 9µm in paint).
