| dc.description.abstract | 隨著科技日新月異，近年來手持式行動產品如手機、數位相機及數位攝影機等消費產品搭配投影能的應用增加，使的投影機的應用愈來愈多元化，讓微投影產品成為近年來的新興科技產品之一。
本論文主要是以設計一DLP微投影光學系統，設計內容包含照明系統的均勻化設計及成像系統的優化設計等，並研究評價投影系統微小化設計的品質與光學效率。
在光源模組上本論文採用高功率的LED燈源並搭配準直透鏡 (Collimator lens)與濾光鏡 (Dichroic Filter) 做為RGB三色光源的合光元件。而在光學引擎的架構設計上以Mirror Type架構取代傳統的TIR架構以降低成本並提高效率，並且利用透鏡陣列 (Lens Array)與4片式投影鏡頭模組的設計以縮小光學體積至6.8 c.c.。設計結果可達到10 lm/W與JBMA均勻度大於90%的設計目標。

| dc.description.abstract | Along with the development of technology, the application of the pico projector becomes diversified in recent years. It’’s widely used in the portable devices like Mobilphone, Digital Camera and Digital Vedio and has become the one of thenew technical products.
This thesis is focused on the optical design of DLP pico-projector system. Thecontent of this design includes the Illumination System and Image OpticalSystem. Then evaluating the optical performance and efficiency of this pico-projector.
In light source module, we choose the high power LED lamp and use collimator lens and dichroic filter for RGB light combiner. In regard to the light engine design, we use a Mirror type structure to replace the traditional TIR structure for a higher efficiency and a lower cost. Besides, we use a lens array and design the Projection Lens with 4pcs lenses to reduce the optical volume to 6.8 c.c.. The simulation result can reach the target that the brightness is higher than 10 lm/W and JBMA uniformity is better than 90%.
