On the fundamental differences between 2D and 3D models of Coherence Scanning Interferometry

Coherence scanning interferometry (CSI) is a non-contacting, optical method that is widely used to measure the topography of engineering surfaces. Several linear models of CSI have been proposed in the literature including the elementary Fourier optics (EFO) Model that represents CSI as a two-dimensional (2D) filtering...
