Standard lamp and diffusers are very important calibration elements , in chapter three , first uv and vuv radiometric standard for calibration are introduced . then the fabrication and characteristics of baso4 diffuser and alminium diffuser are researched , the baso4 diffuser ' s hemispheric reflectance and bi - directional reflectance distribution function were measured and compared with lambtian surface , and the deviation from that of lambtian surface is given . in the experiment , al diffuser ' s brdf is researched , obtain the change of spectral characteristic of al diffuser , compare al diffuser ' s brdf before and after coated with al + mgf2 , and different al diffusers with different surface roughness
铝漫反射板作为一个漫反射光学元件安装在太阳紫外光谱监视器的入射狭缝前，太阳紫外光谱监视器在轨测量时，太阳辐射入射到铝漫反射板后进入入射狭缝，光谱辐照度的角度是变化的，本章测量了铝漫反射的相对双向反射分布函数，研究了镀膜( al + mgf _ 2 )前后光谱反射率的变化，漫反射的光谱特性及漫反射板表面粗糙度对相对双向反射分布函数的影响，使得测量数据反演成为可能。
Thus , it is quite necessary to deeply investigate some related problems , such as stray light transfer , stray light analysis and calculation , stray light suppression method , and baffle system design , bi - directional reflectance distribution function ( brdf ) of material surface , and accurate quantitative analysis and measurement of stray light performance of optical systems , like point source transmittance ( pst ) etc . this paper introduces stray light suppression method
因此，对系统杂光的产生和传输、分析和计算、杂光抑制措施的采用与遮光系统的设计、材料表面brdf以及系统杂光pst的定量测试等方面进行深入研究，是非常有必要的。
