Numerical simulation of the illuminated field P_z obtained by the proposed VCSEL array (128 × 128, pitch of 50 μm). We chose a circular clamped membrane of r_m = 7 mm (circle limit). Our simulation considers a random wavefront error of 0.1 wave rms and includes the Fresnel propagation. To enhance the last effect in the image, the brightness scale is not linear (|I|^0.25).
