| Abstract: | A simple method,based on white light interferometry and optical fiber Michelson interferometer,to measure both large and short optical path difference of Michelson and Mach Zehnder interferometers with micrometer resolution,is described The resolution is determined only by the source light coherence length During the fabricating process of an interferometer,any desired OPD,including zero OPD,can be easily obtained when the method is used online to keep watch on the OPD change |
