The objective is to construct an optical bench that can emulate the conditions encountered in a telescope, even the effects induced by atmospheric turbulence on a wavefront sensor. One of the project’s goals is to devise a novel center detection technique for Shack-Hartmann wavefront sensors that is not influenced by the sodium layer profile, a limitation of existing techniques. Additionally, the project aims to develop tomographic techniques suitable for deployment in giant telescopes. Turbulence tomography is crucial for achieving a wide-field correction. However, in the context of giant telescopes, the computational challenge escalates significantly, necessitating techniques with superior computational efficiency.
