Description
Generalized-Scintillation Detection and Ranging (g-SCIDAR) has proven to
be the most reliable and efficient technique for obtaining the vertical
structure of the atmospheric turbulence through optical means. However,
undesirable turbulence inside the telescope enclosure (dome and mirror
seeing) is intermixed with the results. Processes for rejecting this
contribution have been used indirectly when the vertical wind profiles
are obtained. With a view to introducing the routine use of g-SCIDAR
technique in multiconjugate adaptive optics applications, we propose a
simple method, based on evenness properties with Fourier analysis, for
rejecting the dome and mirror seeing in C2n(h)
profiles. The method is suitable for implementation in real time and
could furthermore be extended to other applications of form recognition,
whenever certain conditions of symmetry are satisfied.
