The basic structure of the Shack-Hartmann wavefront sensor is composed of a microlens array and a CCD camera as shown in figure 2.
WebThe pyramid wavefront sensor of MagAO-X is sampled with 56 pixels across the pupil and has a distance of 60 pixels between the pupils. The OCAM2K camera has a total of 120x120 pixels after 2x2 binning. For … WebThe p yramid wavefron t sensor (P WFS) is a novel concept, which wa s proposed by Ragazzoni for first time in 1996 [1]. The concept of PWFS originates from the standard Foucault knife -edge, and is an effective method for adaptive optics (AO) wavefront sens ing in astronomy. T he historical development of PWFS is described greater
