Scientists introduce an approach, time reversal of variance-encoded light (TROVE), that can demix spatial modes within an ultrasound focus inside scattering media, breaking the resolution barrier imposed by the ultrasound. Optical focusing and imaging with diffuse light at a speckle-scale lateral resolution of ∼5 µm is achieved.
