Realizing high-fidelity optical information transmission through a scattering medium is of vital importance in both science and applications, such as short-range fiber communication and optical encryption. Theoretically, an input wavefront can be reconstructed by inverting the transmission matrix of the scattering medium. However, this deterministic method for retrieving light field information encoded in the wavefront has not yet been experimentally demonstrated. Herein, we demonstrate light field information transmission through different scattering media with near-unity fidelity. Multi-dimensional optical information can be delivered through either a multimode fiber or a ground glass without relying on any averaging or approximation, where their Pearson correlation coefficients can be up to 99%.

计算光场自适应光学成像(CAPIS)技术能够同时记录信号的位置和方向,从光场信息中可得到畸变波前斜率,从而重构波前。研究了CAPIS技术探测光学波前畸变,给出了数值计算模型并进行了仿真分析。结果表明,CAPIS技术可准确地探测低阶像差波前,波前残差方均根值小于0.1λ。建立实验光路并实现了对低阶像差波前的探测,波前残差方均根值小于0.5λ。仿真和实验结果均表明,CAPIS技术可有效地探测低阶像差波前,该结果对探索大视场波前探测方法具有重要意义。
