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

We have developed an algorithm to eliminate the dome seeing contribution to turbulence profiles derived from G-SCIDAR data. The algorithm, based on the parity of functions, is completely automated and it takes only a few seconds to process a full nig

We present the statistical results of the optical-turbulence profiles at the Observatorio del Roque de los Muchachos over a period of six consecutive months. The data were obtained using the generalized SCIDAR technique at the 1m Jacobous Kaptein Tel

In the planning stage of extremely large telescopes, site testing and study of high performance adaptive optics systems plays very important roles. Site testing is a very time consuming task, therefore, we have built a fully automatic device - the CU

We present a new generation SCIDAR instrument that is a fully automatically controlled device with a user-friendly interface. Alignment and observation are reduced to easy and rapid handling without the effort operating in the dome. This instrument i

The statistics of vertical structure of the turbulence affect the complexity of the design and implementation of Multi-Conjugate Adaptive Optics (MCAO) systems. The operation of these systems could be optimized if the stability of the layers were suc

SCIDAR has proved to be the most efficient technique to obtain the optical vertical structure of the atmospheric turbulence measured from ground level. However, the common procedure of obtaining the data, as well as its 'a posteriori' treatment, requ

Knowledge of vertical structure of the turbulence in a site is an essential input for the requirements, performances and operation of Adaptive Optics systems. The statistics of the turbulence intensity and the coherence time of the layers affect the

We describe the current status of the ELP-OA project in which we try to demonstrate in practice that it is possible to measure the tilt of a wave front using only a polychromatic laser guide star and no natural guide star. The first phase of ELP-OA,

Adaptive optics at astronomical telescopes aims at correcting in real time the phase corrugations of incoming wavefronts caused by the turbulent atmosphere, as early proposed by Babcock. Measuring the phase errors requires a bright source, which is l
