Abstract
A new approach using 2D random amplitude-only patterns and look-up table (LUT) is proposed to realize high-efficiency and high-fidelity optical signal transmission in free space through scattering media. Any digital signal only containing 0 and 1 can be optically transmitted with high fidelity in free space through scattering media using only 4 pre-generated 2D random amplitude-only patterns stored in a database. Any grayscale image with values ranging from 0 to 255 can also be transmitted with high fidelity in a direct mode using only 512 pre-generated 2D random amplitude-only patterns stored in a database. For analog signals, a LUT can also be constructed to facilitate optical signal transmission in free space through scattering media. Optical experiments are carried out to verify feasibility and effectiveness of the proposed method. The proposed method can provide a novel insight for high-efficiency and high-fidelity optical signal transmission in free space through scattering media.
