Abstract
Two different types of interferograms and their analysis techniques are being used in precision interferometry. The heterodyne interferometry proposed by Massie et al.1) uses a time-varying interferogram i(x,y;t) with a temporal carrier frequency fa generated by an acousto-optic modulator; g(x,y;t) = a(x,y) + b(x,y)cos(2,rfet +0(x,y)].
