Modeling classical wavefront sensors

WebMeasurements obtained from wavefront sensors are used, in both solar and nocturnal AO, to estimate the wavefront phase, with the use of a reconstruction algorithm. The calculated wavefront is used, through a control system, to determine the shape that a DM has to adapt to compensate the aberrations suffered by the image taken by the telescope.
