Abstract

In the upcoming future the Adaptive Optics group of the Arcetri Observatory aims to integrate and operate two laboratory R&D facilities dedicated to explore new technologies for the operation of the next generation of 40m-class telescopes. In a nutshell they are aimed to: 1) to investigate the benefits of a dual-stage AO system for planet finding instruments (like ELT/PCS) and 2) the identification of a suitable sensor for the control of the piston error on the ELT and GMT. The participation of the Arcetri AO group to the STILES project granted the necessary funding and the perfect time frame to procure the key components required to implement these two facilities. In this paper we will introduce the two R&D facilities, detailing their layout in the laboratory and addressing the specific test cases they will be able to mimic for (e.g. sources, atmospheric conditions, telescope degrees-of-freedom, . . . ). We will then focus on the design of 2 key components of the benches: the custom-made segmented mirror for the AoPetalometer bench and the pyramid wavefront sensors for the AoCascading bench.
