title: Scanning Wiener-fringe microscope with an optical fiber tip.
abstract: A scanning probe optical microscope using the Wiener fringe is presented. The Wiener fringe is formed by a standing wave between the incident and reflected waves on an optically reflective surface and is detected by inserting an optical fiber tip into the fringe-field region. The detected signal is used to maintain the tip-sample distance constant so that a topographic image of a sample can be obtained by a computer-assisted instrument. A spatial resolution of 200 nm has been achieved by observing a sample of known geometry.
