在铝制漫反射板传统工艺的基础上
提出了紫外-真空紫外遥感仪器使用的铝制漫反射板物理磨砂和化学磨砂的新工艺与检测方法
并搭建了主要测试装置。测试结果表明
新工艺的朗伯余弦辐射特性得到明显改善
在0与45入射时
归一化曲线接近标准余弦曲线;300 nm处半球反射率均匀度从0.77提高到0.98;200~400 nm处半球反射率平均提高33%;将其应用于紫外-真空紫外遥感仪器上进行了角度响应测试
漫反射特性明显优于美国2002年发射的同类仪器SBUV/2。
A new method of physical frosting and chemical frosting was presented and a testing equipment was developed on the basis of traditional optical grinding method for aluminum diffuser used in ultraviolet - vacuum ultraviolet remote sensing instrument. The test results indicate that Lambert cosine radiation characteristic of the new method has a distinct improvement
and the incidence normalized curve approaches to the standard cosine curve in the 0 and 45. Moreover
with the new mehtod
hemisphere index of reflection uniformity increases from 0.77 to 0.98 at 300 nm and the hemisphere index of reflection averagely enhances by 33% at 200~400 nm. Proposed method was applied to the ultraviolet-vacuum ultraviolet remote sensing instrument to test the angle response
results show that diffuse characteristic is superior to obviously that of similar instrument SBUV/2 made of America lauched in 2002.
