  1. Research on quantitative relation between multi - angle polarized reflectance and bi - directional reflectance of peridotite

    橄欖巖的多角度偏振與二向反射定量關系研究
  2. 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

    鋁漫反射板作為一個漫反射光學元件安裝在太陽紫外光譜監視器的入射狹縫前，太陽紫外光譜監視器在軌測量時，太陽輻射入射到鋁漫反射板后進入入射狹縫，光譜輻照度的角度是變化的，本章測量了鋁漫反射的相對雙向反射分佈函數，研究了鍍膜（ al + mgf _ 2 ）前後光譜反射率的變化，漫反射的光譜特性及漫反射板表面粗糙度對相對雙向反射分佈函數的影響，使得測量數據反演成為可能。
  3. Standard practice for preparation of pressed powder white reflectance factor transfer standards for hemispherical and bi - directional geometries

    半球狀和二維幾何形狀壓制粉末白色反射系數轉換標準的準備用標準實施規范
  4. 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，對系統雜光的產生和傳輸、分析和計算、雜光抑制措施的採用與遮光系統的設計、材料表面brdf以及系統雜光pst的定量測試等方面進行深入研究，是非常有必要的。
  5. 457nm standard test method for brightness of pulp, paper, and paperboard directional reflectance at 457 nm
