Abstract:	本論文研究以Pigtailed Laser Diode 光學讀寫頭在角度與位移量測的模擬，在論文前半部提出一個Pigtailed Laser Diode 讀寫頭的設計，在設計上分為兩個部份，第一部份設計Pigtailed Laser Diode ，第二部份針對讀寫頭光學設計初階要求、生產組裝要求及實際操作要求，利用Code V光學軟體進行各項分析，讓設計的光學讀寫頭滿足以上要求。論文後半部份探討讀寫頭應用在角度與位移量測的可行性，針對目前結合於原子力顯微鏡的光學讀寫頭，使用Light tools光學軟體進行光學系統重建與模擬，利用光偵測器得到的訊號，找出訊號與待測面偏移的關係。以量測出待測面的傾斜角度與位移，並針對所得之訊號進行分析，判斷是否有訊號耦合的現象。 This thesis is to study the Pigtailed Laser Diode optical pick up head design and simulate the application of angular measurement. The first section of this thesis is Pigtailed Laser Diode pick up head design, and we divided the design for two parts, one is Pigtailed Laser Diode design, and the other is optical pick up head design which included the requirements of optical design manufacture and handling. Analysing and achieving the requirements by using Code V optical software. 　　The next section of this thesis is to study the possibilty of the application of angular measurement. Combining the Atomic force microscope (AFM) optical pick up head to rebuild and simulate the optical system use Light tools optical software and finding out the situation between signal and surface tilt by using PDIC.Then find out tilt angular and displacement on test plane. Finally, we judre the signal is coupled or not by analysing the signal we got.
