【摘要】：針對(duì)星載漫射板遠(yuǎn)紫外波段(140~240nm)的雙向反射分布函數(shù)測(cè)量過(guò)程中,探測(cè)器響應(yīng)線(xiàn)性問(wèn)題和紫外光源穩(wěn)定性差的問(wèn)題,提出一種采用光源監(jiān)測(cè)比例補(bǔ)償?shù)南鄬?duì)測(cè)量方法.根據(jù)測(cè)量方法設(shè)計(jì)了一種基于六自由度轉(zhuǎn)臺(tái)結(jié)構(gòu)形式的測(cè)量系統(tǒng),該系統(tǒng)采用漫射板兩維平移+兩維轉(zhuǎn)動(dòng)、探測(cè)器兩維轉(zhuǎn)動(dòng)的組合運(yùn)動(dòng)形式,可實(shí)現(xiàn)漫射板半球空間內(nèi)任意點(diǎn)、任意方位的雙向反射分布函數(shù)測(cè)量.用所提方法進(jìn)行測(cè)量實(shí)驗(yàn),并對(duì)影響系統(tǒng)測(cè)量結(jié)果的主要因素進(jìn)了不確定度分析,結(jié)果表明總測(cè)量不確定度約為5.5%.
[Abstract]:In the process of measuring the bidirectional reflectance distribution function of spaceborne diffuser in far ultraviolet band (140 ~ 240 nm), the linear problem of detector response and the problem of poor stability of ultraviolet light source are discussed. A relative measurement system based on the structure of six degrees of freedom turntable is designed according to the relative measurement method, which is based on the proportional compensation of light source monitoring. The system adopts two dimensional translation and two dimensional rotation of the diffuse plate. The combined motion of the two dimensional rotation of the detector can be used to measure the bidirectional reflectance distribution function of any point and azimuth of the diffuse plate in the hemispheric space. The main factors affecting the measurement results of the system are analyzed, and the results show that the total measurement uncertainty is about 5.5.
