摘要：
We numerically and experimentally discussed the optimal factors of color focusing through scattering media. Based on the proposed multi-population genetic algorithm that can realize optimal wave front compensation globally, the trade-off between the number of input field modes and the iteration time of the inversion of equivalent transmission matrix is optimized for highest intensity enhancement. It is the first time that the effect of spatial distributions of the input field modes for color focusing is numerically analyzed and experimentally verified.
