Abstract

A high-speed fringe-follower with no mechanical moving parts was constructed. This paper describes the basic principles and the results of the fringe-follower. In this method the phase of the signal is determined by comparing a ratio of two fringe signals, which have phase difference π/2 from each other, with an electronically generated tangent function. The maximum time required to make one measurement was 10 μsec.
