| contents | AMPLITUDE FLUCTUATIONS IN CURVATURE SENSING: COMPARISON OF TWO SCHEMES V. V. Voitsekhovich V. G. Orlov Física, Astronomía y Matemáticas Instrumentation: adaptive optics techniques: high angular resolution The infuence of amplitude uctuations on the quality of phase reconstruc- tion in curvature sensing is investigated. Two curvature schemes are compared: one with two symmetrically-defocused images (Roddier scheme) and one with a single defocused image (Hickson scheme). It is shown that the accuracy of phase recon- struction with the Hickson scheme is strongly a ected even by low-level amplitude uctuations, while the Roddier scheme works well under quite strong amplitude uctuations. 2010 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57115510013 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.46 |
