英文摘要

 

Measurements of the daytime seeing profile of the atmospheric turbulence are crucial for evaluating a solar astronomical site so that research on the profile of the atmospheric turbulence as a function of altitude C2n(hn) becomes more and more critical for performance estimation and optimization of future adaptive optics(AO) including the multi-conjugate adaptive optics(MCAO) systems. Recently,the S-DIMM+ method has been successfully used to measure daytime turbulence profiles above the New Solar Telescope(NST) on Big Bear Lake. However, such techniques are limited by the requirement of using a large solar telescope which is not realistic for a new potential astronomical site. Meanwhile, the AMASP(advanced multiple-aperture seeing profiler) method is more portable and has been proved that can reliably retrieve the seeing profile up to 16 km with the Dunn Solar Telescope(DST) on the National Solar Observatory(Townson, Kellerer et al.). But the turbulence of the ground layer is calculated by combining A-MASP and S-DIMM+(Solar Differential Image Motion Monitor+) due to the limitation of the twoindividual-telescopes structure. To solve these problems, we introduce the two-telescope seeing profiler(TTSP) which consists of two portable individual telescopes. Numerical simulations have been conducted to evaluate the performance of TTSP. We find our TTSP can effectively retrieve seeing profiles of four turbulence layers with a relative error of less than 4% and is dependable for actual seeing measurement.
