Abstract

Propagation of light in communications, medicine, and science is hindered by the phenomenon of optical scattering. Methods to overcome this physical limitation have and continue to be researched. This work attempts to implement the method of wavefront shaping, one of the most successful of these methods. A sequential algorithm was implemented in conjunction with a liquid crystal on silicon spatial light modulator to attempt to achieve wavefront shaping. The phase distribution was adjusted to a phase conjugate-like with the scattering media allowing increased intensity in a given region of interest at the camera plane.
