An optical profilometer is presented working on the principle of focus multiplexing by wavelength encoding. Decoding is performed by lateral dispersion. A detector array shows up a signal distribution whose features accurately monitor the surface position of the sample under test. Versatility, accuracy and dynamical range are the most interesting characteristics of this approach.

Abstract
An optical profilometer is presented working on the principle of focus multiplexing by wavelength encoding. Decoding is performed by lateral dispersion. A detector array shows up a signal distribution whose features accurately monitor the surface position of the sample under test. Versatility, accuracy and dynamical range are the most interesting characteristics of this approach.File in questo prodotto:
