Paper Abstract

The inner scale of atmospheric turbulence is important in atmospheric optics and in particular in laser propagation. Values of the inner scale can be obtained through measurements either of differential angle-of-arrival fluctuations1,2) or of intensity fluctuations3,4)of laser radiation propagated through the atmosphere. Here we propose a method to determine the value of the inner scale based on measurements of laser beam wandering. Laser beam wandering has the advantage of a higher sensitivity as compared with differential angle-of-arrival and seems particularly attractive over short paths. In addition, unlike intensity fluctuations, beam wandering is also sensitive to anisotropy of the turbulence.
