Abstract
Wavefront sensors a key optronic part in any modern telescope This work presents a performance study of the Double-Roof Pyramid wavefront sensor (DR-PWFS), consisting of two orthogonally positioned prisms, which offers some advantages over the Pyramid wavefront sensor (PWFS), one of the most significant being the reduced manufacturing cost. A study will be carried out in Zemax OpticStudio®, which performs simulations based on ray propagation, to verify the performance of the DR-PWFS sensor in comparison with the theoretical results obtained by Object-Oriented Matlab® Adaptive Optics (OOMAO) and to verifying the performance with the variation of some manufacturing parameters, such as “roof angle”, thickness, distance between prisms and alignment variations. It is expected to establish parameters of any errors or aberrations associated with the use of these sensors, in particular the Double-Roof Pyramid and thus create a theoretical and practical support to assist in the development of prototypes on optical benches using DR-PWFS.
