Observation of stellar speckle-patterns is a useful optical remote-sensing technique of terrestrial atmospheric turbulence. The wind velocity (magnitude and direction) at the turbulence layer is determined by movement of the speckle patterns. The altitude and refractive index structure constant of the turbulence layer are also deduced from the peak height and width of speckle-pattern correlation-peak. A new simple system, which consists of an image intensified CCD and a photomultiplier tube attached on a 50 cm telescope, has been developed for observing the speckle-patterns. The system is utilized to continuously monitor the parameters of atmospheric turbulence ranging from 2 km to 20 km. Results of the monitoring measurement over a year are presented.
