摘要

本篇論文主要從光學指頭導航器效率進行改良，在光的傳導過程中嘗試不同的方法，光導管曲面將越彎曲，使得光損耗越多。重新設計光學系統，讓光偵測器準確地感應到光的移動方向，來操作業系統內的滑鼠指標，解決機械件以及電容式觸碰屏所衍生的問題。再用光學軟體進一步模擬、分析和優化，並評估實際製程可行性，加以修正。最後在利用3D繪圖軟體繪製機構件，並模擬此光機構元件，與先前模擬結果有無落差，回頭探討設計過程有無瑕疵，一步步將此光機電元件完成。

The thesis was discussed how to prove the design of OFN(optical finger navigation), and try more methods in light transmission. The more the light guide bent, the more its irradiance be lost. We modify optical system in which sensor detect the light moving better than before. More problems likes mechanical type and controlling mouse of operating system and touching display. Through optimization, simulation and analysis of the optical software: Code V and LightTools, and assess the feasibility of production. Then using 3D graphics software to create institutions components, and using optical software to analyze the differences between past and now. Finding the problem, and finish the institutions components.
