同軸照明設計與應用

Abstract

本論文主要在探討同軸照明之設計，定義同軸照明並利用光學理論闡述其成像品質(MTF)比非同軸好之優點，然後利用同軸照明設計在光學指頭導航(Optical Finger Navigation；OFN)和薄型滑鼠 (flat mouse)，經由數值計算出均勻照明以及不漏光光管並應用在設計中，再藉由光學軟體CodeV和LightTool進一步優化、模擬和分析，並評估製作可行性，然後利用3D繪圖軟體建立機構元件，再次用光學軟體分析其差異，最後製成第一版樣品討論之。

The thesis is primarily based on discussing the design of common-axis illumination. Explaining the optical definition of common-axis and common-axis illumination has better image quality (MTF) than the non-coaxial by using the optical theory. Then using the method of common-axis illumination to design two cases: the optical finger navigation (OFN) and flat mouse. We applied uniform lighting and no leaky light-guide in the design by numerical calculation. Through optimization, simulation and analysis of the optical software: CodeV and LightTool, 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. Finally, the discussion made the first edition of samples.
