IMPROVING THE SENSITIVITY OF ASTRONOMICAL …

WebIn this paper we present a curvature wavefront sensor for the eye. The layout proposed is novel, whilst the algorithm used has been adapted from previously published work [Roddier, F.; Roddier, C. Appl. Opt. 1991, 30, 1325–1327]. The design of the set-up incorporates two field lenses that, together with a beam separator, define the distance ... WebEach wavefront sensor is a split detector such that the halves are 1 mm on either side of focus. In this paper, we describe the extensions to published curvature wavefront sensing algorithms needed to address challenges presented by the LSST, namely the large central obscuration, the fast f/1.23 beam, off-axis pupil distortions, and vignetting ... WebApr 1, 2004 · The curvature wavefront sensor was proposed about 20 years after Shack-Hartmann as a low-order, high-efficiency alternative to the numerous mirror segments and actuators required for Shack-Hartmann systems. The sensor basically compares levels of illumination in two, out-of-focus, beam cross sections that are symmetrical on either side … kitty\u0027s menu north reading
