Imaging through turbid layers by scanning the phase conjugated second harmonic radiation from a nanoparticle

Opt Express. 2010 Sep 27;18(20):20723-31. doi: 10.1364/OE.18.020723.

Abstract

We demonstrate imaging through a turbid layer by using digital phase conjugation of the second harmonic field radiated from a beacon nanoparticle. We show that the phase-conjugated focus can be displaced from its initial position by illuminating the same region of the turbid layer with an angular offset. An image is obtained by scanning the phase-conjugated focus through the turbid layer in a region around the nanoparticle. We obtain a clear image of the target by measuring the light transmitted through it when scanning the focused beam.
