Shower curtain effect: Simulations via wave propagation
Abstract
Shower curtain effect describes distance conditions for enhanced image formation through a scattering medium (curtain). Best images are formed when object is closer to the medium and observer is farther from the medium. A point-scanning method that benefits from shower curtain effect called optical coherence tomography has been simulated using various Monte Carlo algorithms. Here we developed a model that simulates shower curtain effect using a wave propagation equation. The effectiveness of the model is demonstrated using amplitude-type (absorbing) and phase-type (transparent) scattering media. Our FFT-based model is non-scanning and could pave the way for the evaluation of object complex fields through scattering media.
