WebThe wavefront slopes are computed by comparison to a reference and the wavefront through reconstruction from the array of wavefront slopes. There are three basic steps to the analysis process: determination of the spot positions, conversion to wavefront slopes, and wavefront reconstruction. 2.1. Spot position WebOct 19, 2016 · The Performance of wavefront aberration detection and recovery, is limited by the spatial resolution in subaperture, especially for the high-order aberration. To improve the accuracy of wavefront reconstruction, our paper focuses more on the phase retrieval using the stochastic parallel gradient descent (SPGD) algorithm with lower subaperture. In this …
