Conclusion

We have demonstrated the value of the matrix model in the optics of complex media, and outlined the techniques that enable wavefront shaping and image transmission through such media. These techniques have been made possible by the emergence of new wavefront control technologies, which make it possible to control the phase of the optical field, on more and more pixels and at higher and higher speeds. This study was carried out on a stable medium lasting more than an hour, but current technological advances, with the advent of micromirror arrays or ferromagnetic SLMs, now make it possible to envisage similar experiments on stable media lasting less than a second, with the long-term prospect of controlling light waves and imaging in biological media. The study of the statistical properties of the transmission matrix also opens up new perspectives in the fundamental study of complex media,...
