Abstract
We present a novel method for real-time analysis of vibrations in doub le-pulse laser holography. Two pi/2 phase-stepped interferograms are o btained simultaneously. An experimental demonstration gives a phase me asurement with an accuracy of 4 degrees. (C) 1995 Optical Society of A merica.
