Abstract

We present a method to synthesize phase screens for multi-wavelength, atmospheric wave optics simulations using fast Fourier transforms. We validate our work by comparing the theoretical, two-wavelength optical path length structure function to simulated results, and we find the two to be in excellent agreement. Our phase screen synthesis method will be useful in two-wavelength adaptive optics simulations in strong or deep turbulence.
