Paper Abstract

A technique is presented for simultaneous measurement of both the transverse coherence length, r0, and the isoplanatic angle, (theta)0, over coincident paths using a CCD array detection system. The theoretical basis for the measurements is discussed, and results of an extended test using this measurement technique are presented. These results substantiate the independence of the stellar image motion and image intensity fluctuations arising from atmospheric turbulence. Possible applications of this technique to atmospheric propagation studies are also discussed.
