摘要：

A new asymptotic scheme is presented through the computation of [I2] and [I1I2] for waves behind a random phase screen with a power-law correlation. It illustrates the basic idea for an effective new expansion technique that yields a considerably faster convergent asymptotic series for intensity moments in the strong-fluctuation regime. This scheme can also be generalized to the computation of various statistical moments of intensity and log-intensity in continuous media with a power-law spectrum.
