A method is presented for measuring the correlation between the optical fields scattered in different directions by an arbitrary three-dimensional turbid medium. The field angular correlation function is obtained by processing ensemble average intensity data, which are recorded experimentally by a single-channel Shack–Hartmann wave-front sensor. Some general properties of scattered light are expressed in terms of the field angular correlation function, and the correlation function is measured for transmission through a suspension of microspheres under nonballistic transport conditions.
