TL;DR: In this article, a square rule of binary-amplitude modulation was proposed to quantify how many pixels on the spatial light modulator incorrectly modulate the wavefront for the instant status of the medium or the whole system.

TL;DR: Wavefront shaping can be used to achieve optical focusing deep inside scattering media for biomedical imaging, sensing, stimulation, and treatment as discussed by the authors , which can also be used for noninvasive or minimally invasive optical interactions and arbitrary control inside deep tissues.

TL;DR: In this paper, a dynamic mutation operation was proposed to enhance the focusing performance of particle swarm optimization (PSO) in wavefront shaping for focusing light through or inside scattering media, and the simulation and experimental results show that PSO with dynamic mutation demonstrates considerably better performance than PSO without mutation or with a constant mutation.

TL;DR: A square rule of binary-amplitude modulation, directly relating the measured focusing performance with the error in the optimized wavefront, is theoretically proved and experimentally validated and proposed as a novel algorithm, dynamic mutation algorithm, with high adaptability against perturbations by probing how far the optimization has gone toward the theoretically optimum.

TL;DR: A probability-based iterative algorithm combining genetic algorithm (GA) and ant colony optimization (ACO) in which the new solutions can be generated based on a probability map is proposed, able to obtain optimization results with optimal efficiency for single and multiple focuses behind scattering media.
