Fig. 7: Super-resolution reconstruction of binary images by TMBH method.

a Intensity fluctuations of reconstructed images versus increasing OAM-multiplexing channel number. b Comparison between TMBH and CAH methods in terms of reconstruction quality at the same resolution, operating far beyond the sampling criterion limit. c Reconstruction results of the CAH method at the resolution limit of high capacity (γ = 1, K = 81).
