Paper Abstract

There is growing interest in development of electro-optical systems capable of operation over long atmospheric distances in various atmospheric conditions. Some of these systems include laser communications, remote sensing, active and passive imaging, target tracking and designation and laser beam projection (directed energy) systems. As increasingly sophisticated electro-optical systems are used in the atmosphere, the character of the medium becomes important. Optical turbulence is one of the most important characteristics for propagation through the atmosphere. A single ended experimental setup using the Nd: YAG laser operating at 1064nm is used to study the temporal and spatial variations of refractive index structure parameter Cn2 experimentally. In this paper we present the details of the experimental setup used for the measurement of range resolved refractive index structure parameter Cn2, over a two way slant 4.0 km free space laser path. Some of the results obtained using the experimental setup are presented and discussed.
