Design and achromatic analysis of Risley-prism-based beam steering system for space laser communication

Abstract

In order to meet the demand for lightweight and miniaturization of satellite-based laser communication loads, a rotating dual-optical wedge turntable based on the risley prism is designed. A pre-compensation scheme for achromatic is proposed and simulated to verify the feasibility of the inconsistent deflection angle between communication laser beam and beacon laser beam due to different wavelengths.
