Abstract

We have experimentally validated the concept of a differential image motion (DIM) lidar for measuring vertical profiles of the refractive index structure characteristic C_n² by building a hard-target analog of the DIM lidar and testing it against a conventional scintillometer on a 300 m horizontal path, throughout a range of turbulent conditions. The test results supported the concept and confirmed that the structure characteristic C_n² can be accurately measured with this method. Analysis of the effect of scintillation on DIM lidar has been performed. It is shown that the lidar has scintillation resistant capability. Turbulence and lidar calculations were performed. These calculations confirmed that the DIM lidar is practical.
