Paper Abstract

When a laser beam is used to produce a sodium guide star, a Rayleigh guide star can be got as a 'by-product' with the temporal-gating method. In the case of the atmospheric phase distortion is confined to two thin turbulent layers, the sodium guide star is used to measure both the low-altitude and the high-altitude phase distortion (phi) b while the Rayleigh guide star provides a suitable probe signal for the contribution (phi) l of low-altitude turbulence layer. The wavefront distortion (phi) l of low-altitude turbulence layer. The wavefront distortion (phi) h causing by the high-altitude turbulence layer alone is then easy obtainable from (phi) l and (phi) b. The multiconjugate correction system could be founded upon these.
