Web25 jan. 2011 · Modeling the WFSless AO system The intensity measurement of the WFSless AO can be represented in a compact form as I (k) = f (x + u (k)) where I (k) is the intensity measurement at time instant k and u (k) is the control signal to the DM. The unknown wavefront aberration x is represented in the same modal basis as u (k). 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. model of carpet cleaning card https://austexcommunity.com
