Optical state estimation using wavefront data
WebMar 31, 2024 · The RMS wavefront error (found by building a default wavefront Merit Function) is 2.15 10^-3 waves, which may be lower than you might expect by visual inspection of the OPD plot. Note however that the aperture definition of this system uses Gaussian apodization. WebCurrently, the benchmark method for focal plane wavefront sensing is pair-wise DM prob-ing followed by a batch process estimation.14,15 This approach constructs a linear observation of the light field using pairs of opposite DM probing commands and then formulates the wavefront sensing as a least-squares problem.
