Abstract
Optical imaging through complex media such as biological tissue or white paint remains a daily challenge as spatial information gets mixed because of multiple scattering. Without any ballistic light, common microscopy techniques become useless. Over the last decade, spatial light modulators (SLM) have become the indispensable tool to overcome scattering thanks to their millions of degrees of freedom. Wavefront shaping techniques have enabled the control of a transmitted or a reflected field scrambled after propagation, be it via optimization, digital optical phase conjugation or with the measurement of the optical transmission matrix [1]. However, most technique relies on the use monochromatic light.
