摘要
介绍了风云一号气象卫星用的遥感仪器——甚高分辨率扫描辐射计的光学系统设计,包括光学结构选择、成像质量评价、光谱波段截取、视场配准和杂散辐射的抑制等,其中考虑了加工、安装工艺和热适应等问题。仪器成像质量优于1/10瞬时视场,各通道的调制传递函数优于0.3。
The paler describes the optical system design of the Very High Resolution Scanning Radiometer (VHRSR), which has been mounted on FY-1 Meteorological Satellite. It not only involves selection of the optical structure, evaluation of image quality, determination of spectral band, regulation of FOV and reduction of veilingglare, but also considers the effect of satellite environment on the optical system. The dimension of blur point of the optical system is smaller than 1/10 IFOV, and MTF of each channel is greater than 0.3.
