【摘要】：石英漫反射板用于星載大氣痕量氣體差分吸收光譜儀測(cè)量太陽參考譜的觀測(cè)系統(tǒng)中,太陽光譜的測(cè)量精度將會(huì)直接影響痕量氣體反演的精度,為保證載荷全視場(chǎng)太陽光譜的測(cè)量精度,石英漫反射板需具有良好的朗伯特性,在儀器觀測(cè)視場(chǎng)內(nèi)能夠提供均勻的光源。為此,在實(shí)驗(yàn)室利用雙向反射分布函數(shù)(BRDF)測(cè)量?jī)x,選取F4(聚四氟乙烯)粉壓制板作為標(biāo)準(zhǔn)板,采用相對(duì)測(cè)量法對(duì)研制的四種石英漫反射板樣品進(jìn)行了朗伯特性測(cè)量,得出了四種樣品在波長(zhǎng)180~880nm、觀測(cè)角度-70°~+70°范圍內(nèi)的BRDF。通過對(duì)樣品BRDF的分析,篩選出了兩種工藝下的朗伯特性較好的石英漫反射板作為初選樣品,并測(cè)量比較了石英漫反射板和F4標(biāo)準(zhǔn)板對(duì)太陽光的漫反射光譜,石英漫反射板對(duì)太陽光的反射特性較好,可以作為測(cè)量用漫反射板獲取太陽參考譜。為進(jìn)一步的紫外輻照、原子氧侵蝕等試驗(yàn)以及對(duì)比試驗(yàn)提供了數(shù)據(jù)支持。
[Abstract]:The quartz diffuse reflectance plate is used in the measurement system of the solar reference spectrum by the differential absorption spectrometer for trace gases in the spaceborne atmosphere. The accuracy of the solar spectrum measurement will directly affect the accuracy of trace gas inversion. In order to ensure the measurement accuracy of the solar spectrum in the full field of view, the quartz diffuse reflector should have good Lambert characteristics and provide a uniform light source in the field of view observed by the instrument. Therefore, in the laboratory, four kinds of quartz diffuse reflectance plate samples were measured by relative measurement method, using the two-way reflectance distribution function (BRDF) measuring instrument, selecting the F4 powder pressing board as the standard plate, and using the relative measurement method to measure the Lambert characteristics of the four kinds of quartz diffuse reflector. The BRDFs of four kinds of samples have been obtained in the wavelength of 180 ~ 880nm and the observation angle of -70 擄~ 70 擄. Based on the analysis of sample BRDF, the quartz diffuse reflectors with better Lambert characteristics were selected as primary samples, and the diffuse reflectance spectra of quartz diffuse reflectors and F4 standard plates to sunlight were measured and compared. The quartz diffuse reflector has better reflection characteristics of solar light and can be used to measure the solar reference spectrum by using the diffuse reflectance plate. It provides data support for further ultraviolet irradiation, atomic oxygen erosion test and contrast test.
