以雷射二極體為燈源之微型投影機設計
Micro Projector designed by illuminant of Laser Diode
摘要
隨著數位科技在生活當中不斷的增加其重要性，以投影機簡報成為會議場合當中最主要的表達方式。本論文主題為可攜帶式微型投影機，目標是縮小投影系統的整體架構，輕量化減低攜帶上的困難，達到在各種不同的場合中都能隨時傳達重要訊息的目標。 系統以雷射二極體為燈源，以紅色、綠色、藍色三種發光原色的雷射二極體，利用雷射二極體快速點亮的特性，三色光源快速交替點亮，取代一般單片式投影系統色輪分光的應用。設計上搭配單片反射式光閥面板數位微型反射元件，改變數位光訊號處理系統架構，減少一般投影系統中光學元件的使用，以減低成本及縮小體積為前提，設計符合投影機應用原理，且達到輕薄短小及經濟的反射式微型投影機系統。本論文設計內容包括燈源的處理、投影鏡頭設計、整體架構的安排及最後對整體投影結果的模擬分析。

With the increasing importance of application of digital technology in daily life, it is the major presentation briefing by projectors in meeting occasions. The topic of the thesis is “Portable Micro Projector”, being focusing on the minification of entire construction of projectors and decreasing difficulties while carrying them, so to match the targets on sending important messages in different situations. The system illuminant is based on Laser Diode, which includes the three primary colors of light, red, green and blue. Using the characteristics of fast enlightening of Laser Diode, the three lights enlighten themselves quickly one after another, which replaces the general usage of single channel project system that separates the light of color wheels. By using the Digital Micromirror Device of changing the Digital Light Processing System and decreasing the usage of optical components of general project systems, the design of the Portable Micro Projector system is to decrease the cost and the volume in order to match the applications of this micro projector. This essay includes the designs of managing the light sources, the projecting lens, and the whole constructions of simulating the analyses on the results of this project system.
