Abstract

In order to examine the performance of adaptive optics system in the laboratory environment, a new simple laboratory atmosphere turbulence simulator (ATS) is developed which uses the hot resistance coil to generate the hot air turbulence and the fan to control the intensity of the turbulence. The spatial and temporal characteristics of the turbulence generated by the ATS are tested in different experimental conditions by the test system and then compared with the theoretical Kolmogorov spectrum atmosphere turbulence. The results show that the spatial and temporal characteristics of the turbulence generated by ATS have definite similarity with the Kolmogorov atmosphere turbulence under certain experimental conditions. Finally the reason of the difference with theory Kolmogorov atmosphere turbulence is analyzed.
