Angle-of-arrival fluctuation of light beam propagation in strong turbulence regime;

Contrastive experiment of back-scattering echo and beacon angle-of-arrival fluctuation;

Angle-of-arrival fluctuations and its time-averaging effects were studied experimentally and theoretically.

the angle-of-arrival fluctuations of image,image displacement and tilt jitter are often used to investigate the properties of wave fronts corrugated by the atmosphere for high-angular-resolution techniques.

The Triptych Surface Fractal is introduced, and also applied to the interlayer fractures in a dam site in Southwest China, the wavilness angles of these fractures are also calculated.
