A novel optical communication scheme of 2D pattern transfer model based on multi-beam array in complex channel is proposed. The model makes full use of the strong scattering of channel. Spreading of the beams produces an overlapping area at the receiver plane. The reconstruction of the initial 2D pattern spatial position information can be performed by an imaging optics system within the area. The introduction of apparent parameters reduces the complex beam propagation inside two kinds of mediums to a brief propagation only inside air medium, which simplifies the theoretical analysis. A proof-of-concept experiment employs a micro lens array each diameter of which is 15 mm and sea water and atmosphere channel with length of 12.65 m to simulate the strong scattering in real case. The results indicate good feasibility of the proposed model.
