Abstract

A new turbulence sensor has been designed which uses the dispersion in the atmosphere to intersect two beams of narrow band light at different altitudes. The wavefront tilts of the two beams are correlated which gives a weighted average of the turbulence distribution in the atmosphere. By varying the separation of the two beams at ground level, the altitude at which they intersect is shifted from ground level to infinity. The correlation of tilt for several separations allows the distribution of turbulence to be deduced with fair speed and accuracy.
