Study on the Far Field Laser Power Density of the Laser-UAVs with Photovoltaic Panel

Abstract:

The concept of a UAV (unmanned aerial vehicle) with photovoltaic cells powered by a laser beam has been demonstrated as more firm, having higher usable power and more payloads than solar-powered ones, and features wide prospective. This paper analyzes the process of laser energy transmitted in the atmosphere to arrive at the photovoltaic cells. The interaction of laser energy and the atmosphere are analyzed, and the impacts of the diffraction, beam drift caused by turbulence and the aiming precision of the laser launching system on the distribution of laser spot and far field power density. Some bases for laser energy transport are presented.
