本論文採用光線追跡（Ray Tracing）之方法，量測鏡頭在不同條件下的各項光學特性與成像表現。研究基於幾何光學原理，對光學系統進行分析，主要針對系統中孔徑大小以及孔與孔之間間距等參數進行變化，以觀察此類結構在不同位置下對待測鏡頭成像特性的影響。整體研究內容包含實驗設計、數據擬合與結果分析三大部分。 在擬合階段，本研究藉由擬合結果進一步分析出焦點位置、主平面位置與像差等關鍵光學參數。實驗中分別針對沿光軸縱向方向的成像變化，以垂直光軸橫向方向的孔徑變化進行量測，取得不同條件下的光斑影像。針對量測所得數據，將套用不同數學模型進行擬合分析；若擬合結果與原始量測資訊相符，則可進一步建立一套完整描述光線經透鏡後傳遞行為的光線追跡模型，作為後續分析與設計之依據。 ;This thesis adopts a ray tracing approach to measure various optical characteristics and imaging performance of lenses under different conditions. The research is grounded in geometrical optics and focuses on analyzing optical systems by varying parameters such as aperture size and the spacing between apertures. The goal is to observe how these structural configurations affect the imaging behavior of the test lens at different spatial positions. The study is composed of three main parts: experimental design, data fitting, and result analysis. During the fitting phase, the study further analyzes key optical parameters such as the focal point, principal plane, and optical aberrations based on the fitting results. The experiments involve measuring imaging variations along the Z-axis as well as aperture variations along the X-axis to capture the resulting spot patterns under different conditions. The measured data are then fitted using various mathematical models. If the fitting results are consistent with the original measurements, a comprehensive ray tracing model describing the propagation behavior of light through the lens can be established, providing a foundation for subsequent analysis and optical system design.
