Abstract

We introduce a sparsity-constrained optimization framework that accounts for the constraints on wavefront shaping and the light scattering nature in complex media to achieve high-fidelity light manipulation at a frame rate of 22 kHz. Our method demonstrates an 89% and 126% increase in projection accuracy and speckle suppression, respectively.
