Abstract
A high resolution central fringe identification by using the heterodyn e interferometry with a tunable laser-diode and a fixed wavelength las er is presented. It can be operated easily and can be used to judge wh ich arm of the Michelson interferometer is longer. The feasibility is demonstrated and it has 0.2 nm resolution. (C) 1998 Elsevier Science B .V.
