Abstract

The present study is concerned with wavefront shaping algorithms and their performance in noisy environments. Simple sequential algorithms has quite low initial enhancement rate which makes it hard to overcome strong noise. As a result, more complex algorithms which use multiple spatial light modulator pixels were developed. It made it possible to overcome noise at the initial stage faster. One of such algorithms is the partitioning algorithm. The maximum length sequence algorithm considered in this paper is proposed as an improvement of the partitioning algorithm. Both algorithms have similar initial enhancement rates but the proposed one keeps higher rate also at later stages.
