Abstract
The phase correlation function $\langle \exp[i\theta({\bf x+s})-i\theta({\bf x})]\rangle $ for the complex random Gaussian field $\psi ({\bf x})=\vert\psi ({\bf x})\vert{\rm exp}[i\theta ({\bf x})]$ is derived. It is compared to the numerical scattering wave function in the open Sinai billiard.
