MEASUREMENT OF THE REFRACTIVE INDEX STRUCTURE COEFFICIENT CN

Abstract

The refractive index structure coefficient, Cn, is an important parameter for optical propagation in the atmosphere. A theoretical discussion of structure functions is presented to show the origin of the refractive index and temperature structure functions. The equipment used to measure fluctuations in the atmosphere is discussed, and the calculation of the refractive index structure coefficient from these thermal measurements is shown. The details of the experimental evaluation of Cn and the results of Cn calculations are also included.
