Abstract

An optical coherence tomography (OCT) system using a compact fiber source emitting amplified spontaneous emission (ASE) at central wavelength of 1960nm with bandwidth of 40nm is developed to enhance the probing depth in highly scattering material with low water content. Examples of application to paint is used to demonstrate significantly improved penetration depth in high opacity material in the two-micron wavelength regime.
