Scattering-induced entropy boost for highly-compressed optical sensing and encryption

no code implementations16 Dec 2022 Liheng Bian, Xinrui Zhan, Xuyang Chang, Daoyu Li, Rong Yan, Yinuo Zhang, Haowen Ruan, Jun Zhang

In the proposed framework of single-pixel detection, the optical field from a target is first scattered by an optical diffuser and then two-dimensionally modulated by a spatial light modulator.
