Optical profilometry pdf
WebThis approach has two significant implications for profilometry: the longitudinal resolution is decoupled from the lateral resolution, and interference effects can be used to further enhance the longitudinal resolution. We detail the features of coherence scanning profilometry and give some examples. © 1990 Optical Society of America WebAug 1, 2012 · Abstract and Figures Optical digital tomographic microscopy can be used for profilometry. The profile of the surface can be estimated from measurements of the …
