Description
In February 2004 the Cute-SCIDAR instrument was installed at the 1m
Jacobus Kapteyn telescope (JKT) for a systematic monitoring of the
atmospheric turbulence at the Observatorio del Roque de los Muchachos
(ORM). The proper knowledge of the atmospheric turbulence structure is
crucial for optimising the efficiency of adaptive optics systems. SCIDAR
has proved to be the most contrasted and efficient technique from ground
level to obtain the optical vertical structure of the atmospheric
turbulence. The classical and generalised SCIDAR techniques analyse the
scintillation patterns produced at the telescope pupil by the light
coming from the two stars of a binary system. Turbulence profiles as a
function of height, CN2 (h), are derived through the inversion of the
autocorrelation of scintillation patterns. Wind vertical profiles, V(h),
are derived from the cross-correlation of a series of scintillation
patterns relative to a reference pattern.
