摘要

针对我国空间科学的未来发展和应用需求,以及目前星上定标和在轨定标方法的局限性,提出一种基于自发参量下转换效应的自校准宽谱段(450～1500 nm) 辐射基准源设计方案。该辐射基准源系统主要由宽波段参量下转换、观测与自校准复用光路、多路光子计数与符合探测、信号采集与测量控制等4个主要功能模块构成。辐射基准源兼有星上自校准和自主观测功能,能够在不依赖于外部基准的条件下实现高精度的自校准,保障对地高精度观测,为其他卫星有效载荷提供高精度的量值传递标准。

Abstract

For the future development and application requirements of our country’s space science and the limitations of the present satellite calibration and orbit calibration method, a design scheme of self-calibration and wide spectral band (450～1500 nm) radiation reference source is proposed. The radiation reference source is based on spontaneous parametric down-conversion effect. It is mainly composed of four main modules. They are wide spectral band parametric down-conversion, observation and self-calibration multiplexing optical path, multi-channel photon counting and coincidence detection, signal acquisition and measurement control. The radiation reference source has the function of self-calibration and self-observation. It can realize the high precision observation of the earth through its own absolute self-calibration function without external reference. This can provide high accuracy value transfer standard for other satellite payload.
