摘      要：The optical coherence structures of random optical fields can determine beam propagation behavior,light–matter interactions,*** performance makes a light beam robust against turbulence,scattering,and ***,we proposed optical coherence encryption and robust far-field optical imaging *** related applications place a high demand on precision in the experimental measurements of complex optical coherence structures,including their real and imaginary *** studies on these measurements have mainly adopted theoretical mathematical approximations,limited to Gaussian statistic involving speckle statistic(time-consuming),or used complicated and delicate optical systems in the *** this study,we provide:a robust,convenient,and fast protocol to measure the optical coherence structures of random optical fields via generalized Arago(or Poisson)spot experiments with rigorous mathematical *** proposal only requires to capture the intensity thrice,and is applicable to any optical coherence structures,regardless of their type or optical *** theoretical and experimental results demonstrated that the real and imaginary parts of the structures could be simultaneously recovered with high *** believe that such a protocol can be widely employed in phase measurement,optical imaging,and image transfer.
