摘要
It is well recognized that it is difficult to develop an optical system to retrieve effective information when dynamic and turbid water exists in an optical channel. It could be more challenging to incorporate dual or multiple modalities in one optical system. In this Letter, we report a dual-modality optical system for single-pixel imaging (SPI) and transmission through scattering media. A series of mutually-orthogonal random illumination patterns are designed and adopted to realize high-resolution image recovery in SPI. The data to be transmitted are also encoded into random illumination patterns in a differential way, and high-fidelity free-space optical data transmission can be simultaneously realized. Experimental results validate feasibility of the proposed optical system and its high robustness against scattering. The developed dual-modality optical system realizes high-resolution SPI and high-fidelity data transmission in scattering media using only one set of realizations, offering an efficient implementation with reduced power and equipment requirements. The proposed method is promising toward the development of an integrated system with multiple modalities for optical information retrieval, especially in dynamic scattering media.
