Abstract

This paper presents a state-of-the-art overview of fine beam steering mechanisms for free-space optical communication on satellites. Precise beam pointing is a critical task for the successful operation of free-space optical communication systems. Based on past research and ongoing projects, the use of fast steering mirrors (FSMs) is still the most popular solution for free-space optical communication applications. Although a variety of commercial off-the-shelf (COTS) FSM solutions exist, there is limited publicly available data on these solutions in the space environment. Three main actuation principles are considered (electro-static force actuated, magnetic force actuated, piezo-effect actuated) and reviewed using available data from past space missions. The article describes the most important criteria in the choice of a fine beam steering solution for free-space optical communication in space.

自由空间光通信机械微调致动器综述

本文概述了用于卫星自由空间光通信的精细光束转向机制的最新进展。精确的光束指向是自由空间光通信系统成功运行的关键任务。根据过去的研究和正在进行的项目，使用快速转向镜（FSM）仍然是自由空间光通信应用中最受欢迎的解决方案。虽然存在各种现成的商用 FSM 解决方案，但有关这些解决方案在太空环境中的公开数据却十分有限。文章考虑了三种主要的致动原理（静电力致动、磁力致动和压电效应致动），并利用过去太空任务中的可用数据进行了回顾。文章介绍了为空间自由空间光通信选择精细光束转向解决方案的最重要标准。
