(a) Experimental focal-plane camera frame; (b) KL mode 80; (c) impulse response, in symmetrical logarithmic scale for visualisation purpose; (d) reconstructed PFWS response using the convolutional model; (e) experimental linear response, obtained through push-pull process; (f) 1D profile of one sub-pupil of experimental and simulated PWFS signal, with red lines indicating the edge effects due to the convolutional model.
