摘要(中)

在本論文中，主要內容在於建構以生物醫學資料為依據的人類眼球的模型、探討分析視網膜上的影像及人眼散射的討論。其中利用了數學方程式描述水晶體的漸變式折射率以及人眼內各介質色散模型，並使用米氏散射(Mie scattering)模型來模擬人眼水晶體蛋白質造成的散射現象。藉由Code V及ASAP光學軟體的光追跡運算與模擬，此眼球模型的光學表現符合真實人眼的MTF表現與色差行為。在水晶體散射與視網膜眼底漫射模型建構成熟後，這個模型對探討在正常照明情況下以及眩光條件下的人眼視覺表現將會有很高的應用性。

摘要(英)

The main content of this research work includes constructing a biometry-based human eye model, analyzing the image on retina, and discussing the scattering in human eye. The gradient refractive index of the crystalline lens and the dispersive properties of ocular media were modeled by mathematical functions. Mie scattering was introduced to simulate light scatter due to protein particle in crystalline lens. The optical performance of the proposed model was evaluated in CodeV and ASAP. The MTF and chromatic optical powers obtained from the model matched that of physiological eyes. Once the scattering models in crystalline lens and on retina surface are fully developed, this model will be highly potential for investigating visual performance in general and under the influence of glare sources.
