Abstract:	本論文中，我們提出新穎之 BSDF 量測系統，為了達到最終之二維 BSDF 量測資料，我們先嘗試既有之錐光量測系統，鑑於數值孔徑上的限制，遂提出平面成像量測系統並逐步改良至全域成像量測系統。最後，利用全域成像量測系統，可以量測出散射片之穿透散射光角度分佈與反射散射光角度分佈，並且利用一維散角量測系統的實驗結果驗證了全域成像量測系統之準確性。 In this thesis, we propose novel systems for BSDF measurement. In order to obtain the 2-D BSDF measurement data, we try to use the conoscopic system. The conoscopic system has restriction on the numerical aperture, so we propose a planar imaging measurement system and improve it to whole field imaging measurement system. The whole field imaging measurement system can measure both the transmittance scattering distribution and reflectance scattering distribution for different kinds of diffusers. Finally, we use 1-D measurement result to prove its reliability.
