Laser Speckle generated thorugh an objective by Marco Leonetti. 18/06/2021. Algorithm based on the summation of plane waves with K vectors extracted randomply with directions compatible with an objective lens (with Numerical aperture NA) illuimination. The model is for one or two polarization (Polarizations Variable). The software also support the simulation of the focused spot size (focusing Point Spread Function ) of an objective. (Put Sim_Objective to 1) in this case the plane wave dephasing is set to zero (flat wavefront at the objective input).
