Evaluation of the optimal steepest ascent algorithm for focusing light through turbid media

We experimentally compare the optimal steepest ascent algorithm and the sequential method for feedback based iterative wavefront shaping. The former converges significantly faster and leads to a sharp focus behind a turbid medium.
