    摘要:

    风云四号是地球静止三轴稳定平台气象卫星,装载其上的辐射成像仪受剧烈的外热流日周期和年周期变化的影响,扫描机构和主光学系统等关键部件的温度每天波动可达40℃以上。光学及支撑结构如何适应剧烈的环境温度变化,并保证良好的像质,是地球静止三轴稳定平台遥感仪器系统设计的国际性难题。多种特性材料的匹配性设计以及适当支撑结构形式的采用,是避免和减少因温度大幅波动引起的光机变形及成像质量下降的良好策略。在轨数据表明,辐射成像仪克服了昼夜温差大的不利影响,敏感恒星时的弥散斑几乎仅覆盖一个像素,而且正午和子夜结果差别不大。

    Abstract:

    FY-4 is the satellite on geostationary three-axis stable satellite platform. Due to the influence of severe external heat flux on the daily cycle and annual cycle, temperature of the scanning fame and telescope of the imager on board will be fluctuated above 40℃. How to adapt the optical machine structure to the severe environment temperature change and ensure the good image quality are the international problem. Matching design with various material and using proper structure is avoiding and reducing distortion of structure and debasing of image. The data on board indicating, the imager has overcame adverse effect for severe fluctuate when day and night. When star sensing, each diffuse spot almost covers only one pixel, and there is not much difference between midday and midnight.
