Identification and calibration of the interaction matrix parameters for AO and MCAO systems

Neichel, Benoit; Parisot, Amelie; Petit, Cyril; Fusco, Theirry; Rigaut, Francois

Description

New tomographic Adaptive Optics (AO) concepts require a good knowledge of the system geometry and characteristics. These parameters are used to feed the tomographic reconstructors. In this paper we present a method to precisely identify the parameters required to construct an accurate synthetic set of models such as influence functions, mis-registrations, directions of analysis or altitude of the DMs. The method is based on a multi-parameter fit of the interaction matrix. This identification...[Show more]
