Abstract

We report on additional analysis of the Laser Communication System (LCS) experiment. The LCS experiment consisted of transmitter and receiver stations separated by 3 km over a partially land and water horizontal path. An array of fourteen LEDs operating at 808 nm were placed at the transmitter evenly spaced on a 2.4 m bar. The transmitter was observed by a 0.28 m aperture imaging system. Data was collected over fifty days in the summer of 2009 in a variety of conditions. In previous works we reported on the estimated Fried parameter, isoplanatic angle, and turbulence strength estimated along the imaging path. In this work, inspired by other works, we report on the differential tilt-variance observed and how these measurements may be used to estimate other atmospheric parameters. A reanalysis of the original LCS data is presented in that context.
