Paper Abstract

We demonstrate the capabilities of a high-speed phase modulation system based on a digital micromirror device. We use the system to focus light through dynamic scattering materials. We demonstrate up to three orders of magnitude speed improvement respect to previous systems based on liquid-crystal spatial light modulators. Furthermore, the system can be adapted to maintain a focus through a perturbed multimode fiber and help convert it into a micro-endoscope.
