摘要
Controlling the propagation and interaction of light in complex media has sparked major interest. Unfortunately, spatial light modulation devices suffer from limited speed precluding real-time applications (e.g., imaging in live tissue). To address this problem, various embodiments use a phase-control technique to characterize complex media based on use of fast 1D spatial modulators and 1D-to-2D transformation performed by the same medium being analyzed. Some embodiments use a micro-electro-mechanical grating light valve (GLV) with 1088 degrees of freedom modulated at 350 KHz, enabling unprecedented high-speed wavefront measurements. Some embodiments continuously measure the transmission matrix, calculate the optimal wavefront and project a focus through various dynamic scattering samples in real-time, (e.g., within 2.4 ms per cycle). As such, some embodiments improve, by more than an order of magnitude, prior wavefront shaping modulation speed and open new opportunities for optical processing using 1D-to-2D transformations.
