Figure 3

Images decoded from a multiplexed OAM beam and their qualities. (a) Experimental setup. (b) Experimental intensity profiles of images: (b1) diffracted by blazed grating, (b2) reconstructed images encoded and decoded by modes l=8, ±1, ±8, (b3) reconstructed images encoded and decoded by modes l=7, ±1, ±8. (c) Image quality evaluated by normalized intensity variation of the character “u” in Figure 3(b): (c1) horizontal intensity variation and (c2) sharpness calculated from Figure 3(c1).
