Phase ambiguity has often been associated with phase mapping analysis in the measurement of phase change due to laser interaction. This is more obvious in single inteferogram analysis. However several algorithms consisting of two or more interferograms are available from previous researchers to enable such measurement. This book provides the detail development of the system comprising of the interferometer, the fast photography unit and the triggering- synchronizing unit to enable three images of a single event to be captured simultaneously. Simultaneous image capture is the key to the accuracy of the phase measurement because it provides all the three images with the same environment. Two three-interferograms algorithms are described in this book and both of them proved to be able to solve the problem of phase ambiguity.
