    摘要: 本研究主要在架構一套人眼光學量測系統,以量得的數據來完善本實驗室先前所建構的人眼眼球模型,使其更符合真實的人眼光學系統,如以一來,在未來的正常照明條件與眩光實驗會有相當高的應用性。 此量測系統基於資訊影像的完整性(例如散射光),使用二次通過成像(Double-Pass measurements, DP)的架構,含有Badal系統,可方便日後實驗有更多操弄的選擇。 論文首先分析DP的光學理論,並考慮裸眼的光學調制轉換函數(MTF),接著探討實驗裝置,分成兩部分,首先為人工眼的校準裝置,此階段可幫助提升後面人體實驗的經驗及技巧,第二階段為人體實驗,來得到人眼的MTF。 實驗所得結果在趨勢上與現有文獻資料之年輕族群結果大致相符,驗證此實驗系統之可行性,未來可再收取不同年齡層之眼球實驗資料,再與眼球模型所得結果相比較並用以完善眼球模型。 This study focused on the construction of a human-eye optical measurement system. The data is intended for the software eye model previously developed in the research group. Once modified to match the performance of real human eyes, the model is highly potential for investigating visual performance in ordinary lighting and display conditions and under the influence of glare sources. In order to retain the information integrity in the measured images, especially the effect of intraocular scattering, a double-pass (DP) configuration was adopted. A Badal system was included for flexible manipulations in future experiments. The optical theory of DP was first analyzed to derive the modulation transfer function (MTF) of a naked human eye. Two kinds of experiments were then implemented, one with an artificial eye and the other with real human eyes. The artificial-eye experiment served as the system calibration and protocol familiarization. The human-eye experiment provided the images for computing MTFs of human eyes. The experimental results showed the same trend as the data of the young population in the literature, which verified the feasibility of this measurement system. Subjects from different age groups could be collected in future experiments. By comparing the acquired data with the results from the human-eye model, the optical parameters of the eye model could be optimized.
