Simulation of a CW, phase-conjugated light (wavelength λ = 1 μm) back-propagating (from right to left) through a scattering medium of various densities. The 200-μm-by-300-μm scattering medium consists of N randomly positioned, 5-μm-diameter dielectric (n = 1.2) cylinders: (a) N = 200, (b) N = 400, (c) N = 600. The phase-conjugated light back-propagates through the scattering medium and converges at the virtual light source. Intensity of light back-propagating through the scattering medium is depicted.
