摘要：

The zero-crossing rate of differentiated speckle whose intensity is governed by a negative exponential probability-density function (i,e., fully developed speckle) is evaluated in closed form with the use of an exact expression for the joint probability-density function of the intensity and its first two derivatives. The conditional zero-crossing rate of differentiated speckle, given that the intensity is specified, is also obtained in closed form.
