dc.description.abstract | 角膜和眼白主要都是由膠原纖維所組成,但它們卻在可見光波段呈現出截然不同的光學特性:角膜是透明的,而眼白卻呈現出不透明的白色。為了在電腦中模擬出相同的光學現象,我們建造了仿角膜與仿眼白模型並且利用時域擬譜法來模擬分析它們的光學特性。在我們的模擬結果中可以明顯的看出角膜是透明的而眼白是不透明的,為了瞭解是什麼樣因素造成這樣的結果,我們比較角膜與眼白結構上的差異對於光學性質的影響,而它們之間的差異主要包括以下三種:散射物質的間距、尺寸和排列方式。利用時域擬譜法我們分析幾何結構對光學性質的影響。 | zh_TW |
dc.description.abstract | Cornea and sclera each consists of collagen fibrils, but exhibits different optical properties in the visible range. The cornea is transparent, whereas the sclera is opaque and appears white. To analyze the difference of such optical characteristics, we employ the pseudospectral time-domain technique to simulate light propagation through the cornea model and sclera model, respectively. We analyze the effect of geometric structure on the transparency/opaque. | en |
