Abstract

In order to meet the continuing and growing interest in direct optical measurement of the refractive-index profiles of optical waveguides and surface corrugation profiles, we have developed a new filtered-transform scanning microscopic method. The method determines nondestructively the parameters that describe the index or surface profiles.
