摘要
阐述了微纳卫星光学载荷从单一摄像头到应用模式多样的综合系统的发展过程。调研了国外微纳卫星光学载荷的发展现状及特点,如轻小型化、紧凑化、观测任务多样化和视频成像,主要表现在低成本商业遥感应用,适于新技术演示验证、光学载荷图像产品的网络应用、商用现货(COTS)技术应用、模块化技术体系等方面。通过归纳总结得出以下启示:我国微纳卫星光学载荷发展应紧跟国际步伐,瞄准低成本商业遥感方向,建立标准化、模块化微纳卫星光学载荷技术体系;发展颠覆性技术(薄膜衍射成像和液晶可调光谱滤光片用于高光谱成像),积极探索微纳卫星光学载荷研制模式的创新。
This paper describes the development process of the Micro-nano satellite optical payload from single camera to flexible integrated system.The present developing situation and characteristics of Micro-nano satellite optical payload are investigated,for instance,miniaturization,compactness,diversified observation,and video imaging.These are manifested in new technology verification and demonstration,optical payload image product network application,technology of wildly used COTS（commercial off the shelf）,modular technical system,and so on.The paper draws the following revelation：keeping optical payload of Micro-nano satellite in China with the international development,aiming at the direction of commercial remote sensing at low cost,establishing standardized and modular production technology system,developing disruptive technologies such as thin-film diffraction imaging and tunable optical filtering for imaging using liquid crystals,and actively exploring innovative development mode on optical payload of Micro-nano satellite.
