Abstract

A generalized algorithm for use with digital heterodyne or fringe-scanning interferometers was developed that removes many restrictions that had previously applied to the data collection scheme. The required phase steps may be chosen with unequal spacing and to extend over a range greater than 2 pi . The integrating-bucket and phase-step approaches produce identical results.
