Studies of Optical Design and Optimization of Advanced Digitalized Optical System

[[abstract]]本篇論文是研究數位化且模組化的成像與非成像系統的光機設計，運用數位訊號處理器 (DSP)，以及數位光學處理技術 (DLP)設計出數位離散函數運算補償式400倍變焦鏡頭、發光二極體 (LED)光源DLP投影機、以及LED光源數位微反射晶片(DMD)車燈。 此研究成果在400倍變焦鏡頭中，透過數位訊號控制器控制7組電子移動馬達進行變焦及對焦，可有效減輕光學公差對鏡頭調變轉移函數 (MTF)的影響，而LED光源DLP投影機因將傳統色輪移除，並使用自由曲面反射鏡取代平面反射鏡，可大幅減少光學元件的使用量提高整體光通量及縮減投影機體積，另外將DMD使用於車燈光型控制，亦是本研究一大突破，除了可以設計出符合歐規ECE R112車燈規範光型，也可以快速且連續的變換頭燈光型，適應各種特殊路況。 研究中的投影機及車燈在使用LIGHTTOOLS非成像光學模擬軟體設計後，未達預期之光學品質，在使用田口法-主成分分析與模糊理論多重品質最佳化後投影機均勻度達90.2%光通量1430lm效率44.0%，車頭燈的11個亮度規範值也從9個符合優化至完全符合。[[abstract]]This paper aims to study opto-mechanical design of digitalized and modularized imaging and non-imaging system， by using Digital Signal Processor (DSP) and Digital Light Processing (DLP)， to design 400x optical zoom lens， which is compensated by digital discrete function computation， Light Emitting Diode (LED) luminance DLP projector， and car lamp design by applying Digital Micromirror Device (DMD) of LED illumination. This research result can be applied to 400x optical zoom lens， and by using digital signal controller which controls 7 sets of electro-driving motors to zoom and focus， it can effectively reduce the influence of the optical tolerance on the Modulation Transfer Function (MTF) of the lens. Furthermore， LED illumination DLP projector， without traditional wheel but with free form reflector to replace planar reflector， can significantly reduce required quantity of optical components， enhance overall luminous flux， and contract size of the projector. In addition， it is an innovation that this research applies DMD to control light-type of car lamp， which can not only be designed in accordance with ECE R112 light-type of car lamp standard within European standard， but can also be designed to shift light-type of the headlight rapidly and continuously， in order to cope with various road conditions. The projector and the car lamp equipped with LIGHTTOOLS non-imaging optical simulation design software can’t achieve expected optical quality. But by using Taguchi-PCA and Fuzzy multiple quality optimization， the evenness of the projector achieves 90.2%， luminous flux 1430lm， efficiency 44.0%， and 9 luminous values in the headlight conforming to the standard increase to the full counts of 11
