Abstract
The measuring principle and basic composition of the CLIAM (Coherence Length and Isoplanatic Angle Measurer) are presented and the results measured at Yunnan Observatory in Kunming are reported in this paper. The measured results are compared with the calculated values based on C2n altitude profile measured by using ballon-borne macrothermal probe. Finally, some factors, which could have an effect on measuring validity, are analyzed.
