Lensless imaging based on coherent backscattering in random media

Lensless imaging based on coherent backscattering in random media

We studied lensless imaging due to coherent backscattering in random media both theoretically and experimentally. The point spread function of the lensless imaging system was derived. Parameters such as the volume fraction of the scatterer in the random scattering medium, the diameter of the scatter...
