Abstract
Scanning white-light interferometry is widely used for the microstructure a nalysis of technical and biological specimens. For each pixel in the focal plane of the apparatus a white-light interferogram is acquired and evaluate d by means of an algorithm. We discuss some properties of mathematically op timal evaluation methods and the best possible achievable resolution derive d therefrom depending on the setup parameters. A comparison of the results to one of the algorithms described in the literature is given. (C) 2001 Opt ical Society of America.
