A Simplified Model for Optical Systems with Random Phase Screens

Abstract

: A first-order optical system with arbitrary multiple masks placed at arbitrary positions is the basic scheme of various optical systems. Generally, masks in optical systems have a non-shift invariant (SI) effect; thus, the individual effect of each mask on the output cannot be entirely separated. The goal of this paper is to develop a technique where complete separation might be achieved in the common case of random phase screens (RPSs) as masks. RPSs are commonly used to model light propagation through the atmosphere or through biological tissues. We demonstrate the utility of the technique on an optical system with multiple RPSs that model random scattering media.

The enhancement effect of backscattering for laser propagation through turbulent atmosphere

“…3 Effect of propagation distance and turbulence atmospheric intensity on enhanced backscattering3 SIMULATION OF BACKSCATTERING ENHANCEMENT EFFECT3.1 Phase screen simulationAt present, the simulation methods of turbulence atmospheric include theoretical analysis, experimental verification and numerical simulation. With the rapid development of information technology, numerical simulation[17][18][19] has increasingly become an effective research method for turbulence atmospheric in view of the problems such as the idealization of the parameters of theoretical analysis and uncontrollable parameters of experimental verification.…”
