WebOptical profilometry uses white light interferometry to generate a 3D image of the sample surface with a height resolution better than 1Å. Uses Film thickness from an edge … WebDec 29, 2024 · Surface reconstruction for micro-samples with large discontinuities using digital holography is a challenge. To overcome this problem, multi-incidence digital holographic profilometry (MIDHP) has been proposed. MIDHP relies on the numerical generation of the longitudinal scanning function (LSF) for reconstructing the topography …
