RUIZ, P.D. and CHAKRABORTY,S., 2013. Tomographic imaging of all orthogonal components of the displacement field in weakly scattering materials using wavelength scanning interferometry. Presented at: OCT4NDT Symposium: First International Symposium on Optical Coherence Tomography for Non-Destructive Testing, 13th-14th February 2013, Linz, Austria.
This paper presents a wavelength scanning interferometry system which provides displacement fields
inside the volume of semi-transparent scattering materials with high spatial resolution and threedimensional
displacement sensitivity. This technique can be viewed as frequency multiplexed sweptsource
OCT in which different channels carry information for specific displacement sensitivities.
