Abstract
A polarization interferometer which measures optical path differences with improved accuracy control is presented. The approach makes use of four signals in quadrature, computing the phase with an algorithm ins ensitive to laser power drifts. Experimental results of the interferom eter's performance are given under;laser warmup conditions, and with l ong-term monitoring of optical path differences. (C) 1995 American Ins titute of Physics.
