Modal characterization of the LG beam superposition.
The first (a) experimental and (c) theoretical principal components deduced from 900 random LG beam superposition (l = [0, 1] and p = [0, 1]), (b) first two principal component projections (experimental), (d) experimentally measured individual beam detection errors for a different set of 100 random superpositions. The intensity error is defined as (ci - mi)2 where ci and mi are the, encoded and respectively measured, real amplitude superposition coefficients.
