Remote Sensing and Imaging Physics: Developing new metrics for deep turbulence effects on laser propagation through long path
Abstract
Many directed energy applications are significantly limited by atmospheric turbulence. This project seeks to develop metrics to effectively characterize the impact of deep turbulence on laser beam propagation over a long path. The goal is to develop a clear understanding of the problem and optimize the methods of mitigating the strong turbulence effects for space based imaging through critical examination of turbulent eddies’ structures in spatial, temporal and related spectral domains. The study will employ expertise from complementary field of computational fluid dynamics in collaboration with the AFRL mentor having several years of expertise in laser based emote sensing and space imaging. The investigation is expected to result in better understandings of power-spectra for the refractive index fluctuations leading to improved adaptive optics technologies.
