Wavefront Shaping in Complex Media:
From the Compensation to the Exploitation of Randomness

Sebastien M. Popoff

CLEO 2017 - San Jose, CA (USA), May 16 2017

Abstract: In the past ten years, many techniques were developed to control light propagation in complex transmission media using spatial light modulators. It involved applications in numerous fields including biomedical imaging and therapy, fiber endoscopy, cryptography, optical micromanipulation, optical spectroscopy, telecommunications and random lasers and also served as a tool for fundamental studies of light propagation in complex environments.

Highlights

From diffusive to ballistic-like transport in absorbing media

[S.F. Liew et al., Phys. Rev. B, 89, (2013)]

Intuitively, absorption of light is detrimental for imaging as it reduces the intensity of the image we see. On the other hand, scattering is also a known obstacle for imaging as it mixes light sending it in all the directions. In the present paper, S.F. Liew and his collaborators from Yale University (CT, USA) and the University of Twente (The Netherlands) show that, contrary to appearances, absorption can in fact help light to follow a direct path through disordered media.
