Abstract
Achieving high-precision light manipulation is crucial for delivering information through complex media with high fidelity. Digital micromirror devices (DMDs) have emerged as a promising candidate as high-speed wavefront shaping devices but at the cost of compromised fidelity, largely due to the limited degrees of freedom and the challenge of optimizing a binary amplitude mask. Here we leverage the properties of sparse-to-dense transformation in complex media and introduce a sparsity-constrained optimization framework. The proposed optimization framework could enhance existing holographic setups without changes to the hardware, and enable high-fidelity and high-speed wavefront shaping through different scattering media and platforms.
