<br>
</span><i><span style="font-size:12.0pt;color:black">Wavefront shaping has been an active research area over the past decade. Its ability to control light transmission through or into a scattering medium has significant biophotonics, computation, imaging, encryption
and other applications. In this talk, I will discuss the various advancements we have made in wavefront shaping and talk about the use of wavefront shaping in biophotonics. I will also discuss two recent and surprising findings in our wavefront shaping work.
The first is the intentional combination of wavefront shaping and a controlled scattering medium to create novel optical system – in effect, turning scattering from a ‘foe’ to a ‘friend’ for wavefront shaping. The second is the complete dropping of phase characterization
in a new class of ‘wavefront shaping’ methods.</span></i><o:p></o:p></p>
