Abstract

We introduce a phase conjugation method that utilizes multiple incoherent guidestars to control light in complex media. The technique involves the characterization of mutually incoherent scattered fields, followed by their time-reversal. With this approach, we achieve precise light focusing on individual and multiple guidestars, as well as efficient energy delivery to an extended target through scattering media. This method has various potential applications, including optical manipulation, targeted stimulation and deep optical imaging.
