Multi-aperture receiver structure. (a) Optical antenna array distribution for \(M = 2\), 5, 9, 16. (b) Schematic of the programmable optical processor connected to the OAA. (c–e) Mean received power (c), standard deviation (d), and three-sigma limit (e) as a function of the number of apertures for different separation distance \(d_S=5\), 11 and 30 cm, and the three considered turbulences \(C_n^2= 10^{-13}\), \(10^{-14}\), and \(10^{-15}\) \([\text {m}^{-2/3}]\). \(d_R = 4.5\) cm. \(\overline{P_{rx}}\) is calculated by summing coherently the contributions of the M apertures. \(\overline{P_{rx}}\) and \(\sigma _{rx}\) have been calculated as the average of 100 simulations.
