Atmospheric-turbulence measurements using a synthetic beacon in the mesospheric sodium layer.

We have performed what are, to our knowledge, the first measurements of wave fronts propagated through atmospheric turbulence with the use of a synthetic beacon in the mesospheric sodium layer. The synthetic-beacon wave fronts showed reasonable agreement with those from reference stars. The sodium-layer beacon performance was also compared with that of beacons produced by Rayleigh backscatter in the 6-20-km altitude range.
