Comparative Analysis of Numerical Simulation Techniques for Incoherent Imaging of Extended Objects Through Atmospheric Turbulence
Computational efficiency and accuracy of wave-optics-based Monte–Carlo and brightness function numerical simulation techniques for incoherent imaging of extended objects through atmospheric turbulence are evaluated. Simulation results are compared with theoretical estimates based on known analytical solutions for the modulation transfer function of an imaging system and the long-exposure image of a Gaussian-shaped incoherent light source. It is shown that the accuracy of both techniques is comparable over the wide range of path lengths and atmospheric turbulence conditions, whereas the brightness function technique is advantageous in terms of the computational speed.
