The hybrid Shack-Hartmann/G-SCIDAR instrument

摘要

We have built a hybrid turbulence profiler measuring simultaneously the atmospheric turbulence structure with a Shack-Hartmann wave front sensor and a G-SCIDAR (scintillation sensor). This is the first instrument combining two different techniques to measure simultaneously the turbulence structure. The hybrid profiler has been installed at the Carlos Sánchez Telescope (TCS) at the Teide Observatory (OT), in Tenerife Spain. The G-SCIDAR arm is already working properly and we are still testing the Shack-Hartmann arm.
