Abstract

An interferometer including a master laser, a slave laser and optical elements is provided. The optical elements direct and combine a master laser beam and a slave laser beam into a sensing phase measurement loop to provide a sensing beat signal and a reference phase lock loop to provide a reference beat signal. An electronic circuit portion is coupled to receive the sensing and reference beat signals. The electronic circuit portion includes a clock, at least one numerically controlled oscillator, at least one mixer and an interferometer output. The at least one numerically controlled oscillator has a clock input coupled to the clock. The at least one mixer has a first input to receive the sensing beat signal and a second input to receive an output of the at least one numerically controlled oscillator. The interferometer output is coupled to receive an output of the at least one mixer.
