dc.description.abstract | Pyramid wavefront sensors are widely used in adaptive optics systems, due to their advantages in terms of sensitivity with respect to other wavefront sensors such as the Shack-Hartmann. However, especially in extreme adaptive optics applications, Non-Common Path Aberration (NCPAs) cause image distortions that can hinder the scientific throughput. NCPAs are usually corrected introducing offsets on the pyramid closed-loop control systems, but the consequent increase in the size of the star image on the pyramid pin leads to a decrease in sensitivity that compromises the aforementioned advantages. In principle, these offsets can be counter-balanced by introducing an active optical element in the wavefront sensing channel, recovering the full sensitivity of the pyramid. In this framework, we are studying the capability of Multi-Actuator deformable Lenses to recover such NCPAs. We present in this paper the result obtained on the test-bench that has been realized at CNR-IFN Institute in Padova, with the collaboration of INAF-Padova, aiming at the NCPAs correction by the means of a multi-actuator deformable lens inserted in the sensing path, in order to recover the optimal working conditions and the ideal magnitude gain of the pyramid. | en_US |
