Abstract

Technology has long provided defenders a means to overcome numerical disadvantage—Greek fire against besieging fleets, radar against massed bomber formations. Today, the proliferation of low-cost drones presents a similar asymmetric challenge. Countering this threat will require a paradigm shift away from high- performance, high-cost consumable ordnance. Directed energy systems provide one such approach. Like many technologies, laser-based directed energy systems have gone through cycles of excitement followed by disappointing failures. However, the convergence of fiber laser amplifiers and inexpensive high-speed computation has finally made practical systems achievable. In this talk I will provide an overview of modern directed energy systems, focusing on topics relevant to Mechanical and Aerospace Engineering and centering on beam control—the systems responsible for compensating for atmospheric turbulence and boundary layer effects around aircraft. After reviewing how turbulence affects laser propagation and imaging, I will discuss compensation approaches used in modern systems. The talk will conclude with open research and engineering challenges.

Bio

Jeremy Bos is an Associate Professor of Electrical and Computer Engineering at Michigan Technological University. Before joining Michigan Tech, Bos worked as a NRC Postdoctoral Fellow under the Research Associateship Program with the US Air Force Research Lab in Kihei, Hawai’i. He received his PhD and BS from Michigan Tech in 2012 and 2000 respectively and his MS from Villanova University in 2003. Before returning to academia Bos spent ten years working as an engineer in the defense and automotive industries. He is a senior member of Optica, IEEE, and a Fellow of SPIE and a licensed professional engineer. Bos is an author on over 100 scholarly works including 7 patents. His research interests are in atmospheric optics, laser beam propagation, optical remote sensing, and scene recovery.
