Abstract

Synchronous detection of randomly phase-modulated interferograms is examined for the cases of low and high SNR. Long-average phase estimates exhibit (time × bandwidth)−1 dependence and give useful results with low SNR and σϕ < π. Optimum averaging times are determined for phase tracking in the case of relatively high SNR.
