提出了一种利用IRAS、MSX星表数据,建立空间光学辐射特性模型。在确定地基光学系统参数后,经过对星表数据进行坐标转换和天文修正,得到观测天区的恒星分布和红外辐射特性数据,并利用计算机绘制深空点源图像。
A model of spatial optical radiation characteristics was proposed based on IRAS and MSX catalog data. After the parameters of foundation optical system are determined, the star distribution and the infrared radiation characteristics of the observation area are obtained through the coordinate conversion and the astronomical correction of the data of the astronomical surface. The source image of deep space is drawn by computer.
