Abstract: Stabilization of the phase of the radiation utilized in a plural beam interferometric-type system is accomplished. Monitoring of the intensity of the interfering beams of radiation is performed so that a correction signal is generated. By applying the correction signal to control means, the speed of propagation of at least one of the radiation beams is altered to maintain a constant phase relationship.
