Modal characterization of the diffracted Hermite-Gaussian (HG) beams from a random aperture.

(a) The first 9 principal components of the measure, (b) analysis for the first two principal components, (c) analysis for the second and third principal components and color coded for the m and n indices of the HG beam modes (m = [0, 6], n = [0, 6]) and (d) the 3D chart of the confusion matrix linking the expected and detected indices of the HG beam modes.
