Abstract

Development of a passive optical method for estimating the atmospheric turbulence strength (refractive index structure constant C n 2 of atmosphere) from image jitter is discussed. It is proposed that high rate digital camera and fast parallel 2-D image processing algorithms are used for real-time C n 2 measurements. A comparison is made of the results obtained by passive and active optical and acoustic methods.
