Paper Abstract

We present a simulation method for studying turbid media in the optical field based on circular Gaussian distribution (CGD) model, by which the transmission matrix, representing the modulation of a turbid medium on the amplitude and the phase of incident light, can be generated directly and efficiently. As an application example, light refocusing through a turbid medium is realized employing the CGD model approach, combining with wavefront–phase modulation technique and Fresnel diffraction theory, which is applied to describe the light propagation between optical elements of the entire system. Simulation results based on this approach agree well with theoretical analysis for light refocusing, which can validate the feasibility of CGD model. This work can be used for exploring the potential applications of turbid media in the optical field further, especially for developing new microscopic imaging technologies beyond the diffraction limit.
