Abstract
This paper describes a new interferometric method to measure length changes precisely. Frequency of a laser which is locked to one of interference fringe intensity peaks of an interferometer so that it may change linearly proportional to displacement given to one of the interferometer mirrors. The frequency shift is determined by direct beam frequency counting referring another frequency stabilized laser. Resolution of nm is achieved.
