Multi-wavelength laser system propagation experiments

Atmospheric propagation experiments for active and passive EO systems were performed over a 2 and 8 km path. Single and double path propagation effects were studied using retroreflectors and hot point targets. The systems used include laser systems at 1.5 and 3.5 mu m wavelength as well as imaging systems in the visible, 1-2 and 8-9 mu m regions. A scintillometer operating at 0.8 mu m wavelength was also used for the shorter path. Experimental data will be presented and evaluated concerning statistics. The results will be discussed mainly from a laser countermeasure point of view.
