How To Take Photographs Through Opaque Objects

May 6, 2010 | Source: the physics arXiv blog

Langevin Institute physicists have devised a way to reconstruct randomly scattered images to allow pictures to be transmitted (or viewed) through certain kinds of opaque objects.

Just send several known wavefronts through the material and record how they are distorted. The “transmission matrix” (how light is scattered by the opaque medium) can be deduced from the difference between the projected and transmittted wavefronts. Then send the inverse of the transmission matrix.
