摘 要:A spatial modulation method for electronic speckle patterns is *** fringes are produced by object tilting and the phase field of deformation is demodulated by Fourier *** principle is *** system and some typical experimental results are *** results prove that by using object tilting method speckle patterns can be modulated very well and the out-of displacement of an object can be obtained effectively.
