【 摘 要 】

A novel technique is given and implemented to generate correlated phase screens that are used in the study of laser propagation through turbulent atmosphere. The method can generate random fields with nonzero expected values and is applied to simulate equally and arbitrary spaced phase screens. In both cases, it proves to be very computationally efficient.
