Abstract

In this paper, we report an approach to realizing optical data transmission through dynamic scattering media using a pixel-to-plane data encoding strategy, and high-fidelity and high-security transmission can be realized. A signal is considered as a sequence of separate pixels which are sequentially encoded. We generate a series of 2D patterns as information carriers to be used in the optical transmission channel. To suppress noise, a differential protocol is designed and applied. In the designed optical system, numerous keys are generated to guarantee the security. The absorptive filters are used, and ciphertext can be obtained. Our experimental results illustrate validity of the method. Only when the keys are correct at the receiving end, the encoded data can be retrieved. It is expected that this approach can be useful to secure free-space optical data transmission through dynamic scattering media.
