Confocal interference microscopy can be used to obtain phase information in a confocal microscope. Different methods of recovering phase are discussed. A fiber optic confocal interference microscope has been developed. Confocal interference can be used to investigate aberrations in a confocal microscope. Methods of profiling surfaces are reviewed. Depth profiling of stratified media is considered.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
