Abstract

In the last decades, Adaptive Optics have gained a great importance in improving the observatories capabilities all over the world, and the complexity and dimensions of deformable mirrors have grown rapidly, making necessary the development of clever ways to perform their optical calibration. Here we propose the study of a procedure based on the accurate local calibration of the position sensors. This approach would have a huge impact on both time and cost with respect to actual approach, consisting in the measurement of the actuators influence functions in full aperture. After the development of a simulation tool, able to prove our idea, we will test the new approach on deformable mirrors which are now under production.
