Abstract
We introduce a novel feedback-based wavefront shaping algorithm “dynamic mutation algorithm (DMA)”, which has high adaptability and a unique recovery ability. The optimization is based on the real-time error rate, which implies how far the optimization has gone toward the theoretical optimal result. The phase map is dynamically mutated according to the instant optimization state. When it encounters alteration in the transmission matrix, the diminished focus can be recovered, which no other current algorithms can achieve as they are usually heavily based on previous iterative results. The new algorithm has the potential to boost many applications in unstable scattering environments.
