Imaging through Turbid Media Using Phase Conjugation

Open Access Open Access


We describe how second harmonic nanoparticles inserted deep inside tissues can be used as beacons to enable the formation of a phase conjugate wavefront that propagates through the scattering tissue and comes to a sharp focus inside. We show how the optical memory effect can be used to scan the phase conjugate beam in 3D inside the tissue and obtain an image. Article not available.
