Fig. 5.10 Effect of beam size and motion 5.4 Summary The influence of the operation-point (initial) phase noise on the accuracy of Amplitude-Fluctuation Electronic SpecklePattern Interferometry is discussed. It has been demonstrated that the use of carrier fringes and analysis in the spatial frequency domain reduces the noise associated with a slow fluctuation of the operation-point phase. It has been found that movement of the interferometric beams can compromise the frequency domain analysis as it can vary the spectral peak height.
