本論文提出了一種導光棒元件的設計概念，利用高溫刀片於導光棒表面雕刻出結構，採用雕刻自動化架構且針對該架構的重複性與精準度進行了定量分析，再藉由調整導光棒上凹槽條紋的週期與深度，進一步控制出射光的能量分布，PRNU數值小於30%。設計的導光棒表現能夠達到相關規範要求，最後透過量測雕刻完成品上的刻紋週期與深度數值來進行模具製作以便後續量產作業的進行。導光棒為接觸式影像感測模組中重要的元件之一，本研究提出實驗性的設計方式可有效降低設計與量產之間的表現差異性，同時降低修改模具的可能性。;In this thesis, a novel concept for the design of a light guide bar has been firstly proposed. We apply a certain blade with high temperature for shaping the necessary grooves on the bottom of the light guide bar. All the sculpturing parameters, including the repeatability of the light guide bars, the accuracy of the groove periods, and the precision for the groove depth, are extensively verified. The groove periods and depths have been carefully optimized in order to have uniform output light distribution. Generally, the PRNU value is requested as low as less than 30 %. The simulation design is then realized in mass production and greatly help the production time and cost.
