An active wavefront sensor to make feasible adaptive optics on 100-m class telescopes
TL;DR: In this paper, a conceptual layout for an active control of the wavefront sensor, in order to reach the best mechanical positioning of these star enlargers, is presented, and an algorithm to determine the effective pupils positions by simple movements and apply the requested displacement through commercially available piezoelectric actuators, shown in a preliminary opto-mechancial design of such wavefront sensors.

Hartmann data analysis for PLATO TOU EM
A. Cottinelli,Daniele Vassallo,Jacopo Farinato,Demetrio Magrin,Federico Biondi,P. Royer,Roberto Ragazzoni,Isabella Pagano,Marco Pagliazzi,Andrea Novi +9 more
TL;DR: In this article , the Hartmann mask was used at the Telescope Optical Unit (TOU), aligned at ambient and characterized at the operational temperature, and a Focal Plane Array bearing the detectors and delivered after coupling with the Front End Electronics.
