摘要
An optical technique is described that determines the path-averaged value of a refractive-index structure parameter at 10.6 mu m by use of a pulsed coherent CO2 Lidar in direct detection and hard-target returns. The Lidar measurements are compared with measurements taken by a 0.9-mu m scintillometer and temperature probe (with humidity corrections). The experimental results show good agreement far C-n(2) greater than or equal to 10(-14) m(-2/3). With respect to practical applications the new technique permits C-n(2) lidar measurements in a neutral meteorological situation to an unstably stratified convective boundary layer over long ranges (1 km or more).
