Electric field Monte Carlo modelling of transmission matrix of turbid medium
In this paper, we report a high-speed electric field Monte Carlo simulation to calculate the transmission matrix of turbid medium. To accelerate the simulation speed, the Monte Carlo process is performed on a GPU. By the utilization of Mie scattering theory and random sample method in the simulation, the propagation of electric field in turbid medium can be precisely studied. Through the electric field Monte Carlo simulation, we derive the transmission matrix for a focal spot in the turbid medium. Based on this transmission matrix, the optical phase of input light is modulated to restrain the speckle noise and a high-quality focal spot can be reconstructed inside a turbid medium.
