This effort characterizes proper sampling of laser speckle in wave-optics simulations, with an emphasis on active imagers in outdoor environments. Modeling of performance degradations induced by speckle is critical in the design of such devices. We e

We use Mellin-transform techniques to derive generalized expressions for the piston-removed and piston-and-tilt-removed anisoplanatic error in non-Kolmogorov turbulence with a finite outer scale. We use these expressions to investigate the behavior o

We investigate the effect of non-Kolmogorov turbulence on the coherent return of a Gaussian beam illuminating a space object. This scenario is relevant to a number of sensing and imaging modalities including both Free Space Optical Communications Spo

A tunable mid-IR source based on four-wave mixing in Xe-filled hollow-core photonic crystal fiber is investigated numerically. Tunability from the 1.95μm pump through the mid-IR is demonstrated. In spite of higher loss, modeling suggests that smalle

We evaluate the piston-removed anisoplanatic error for smaller apertures imaging over long horizontal paths. Previous works have shown that the piston and tilt compensated anisoplanatic error saturates to values less than one squared radian. Under th

We compare several modifications to the open-source wave optics package, WavePy, intended to improve execution time. Specifically, we compare the relative performance of the Intel MKL, a CPU based OpenCV distribution, and GPU-based version. Performan

Phase screen-based wave optics simulations are a fundamental tool used by researchers seeking to understand the effect of atmospheric turbulence on laser beam propagation and imaging. Most wave optics packages are either themselves proprietary or rel
