Full polarization optical profilometry [PDF]

open access: yesJournal of the Optical Society of America A, 2012
Optical digital tomographic microscopy can be used for profilometry. The profile of the surface can be estimated from measurements of the complex diffracted far field obtained when the sample is illuminated successively under various incidences. Outside the validity domain of perturbative theories of diffraction, the profile is determined by using an ...
