隨著光儲存系統容量的提升，對於光碟機特性的要求也逐漸提高，因此必須設計出更好的光機電整合系統才能符合未來的光儲存系統的需求。本研究的目標為建立出一套光學模擬系統，進行光碟機中光電訊號與控制系統的模擬分析，並討論光路系統與伺服控制系統間的關係。
本文將以幾何光學與繞射光學理論為理論依據，首先介紹光碟機的光路系統及光電訊號原理，接著介紹系統的伺服控制原理，然後說明模擬系統的架構。本研究從建立光碟機光路模型為出發，接著模擬聚焦誤差光電訊號、射頻光電訊號與循軌誤差光電訊號，並將模擬結果與實驗結果進行比較，以驗證其準確性。由於光碟片偏擺的容忍度也隨著儲存容量的提高有更高的標準，本研究接著加入光碟片偏擺效應，討論偏擺對於光電訊號的影響。然後模擬光碟片的動態行為，並以循軌誤差訊號為指標，模擬出光碟片離心與光碟片晃動對於循軌誤差訊號的影響，最後加入傾斜伺服控制器修正由於光碟片偏擺所產生的影響。
因此可藉由本論文提出的光碟機光路系統模擬分析，提供可信度高的模擬結果，使研發人員於尚未實際設計出光碟機實體時，藉由該模擬系統就可以提供可信的結果，已進行下一步設計。

With the development of an ultra-high capacity optical storage system, a high performance opto-mechatronics system must be designed to conform the need for the future optical storage system. The objective of this thesis is to built an opto-mechatronics simulation system to integrate the electro-optical and control system in a DVD system. Based on the simulation results, discussion of the relationship between electro-optical system and servo control system is depicted.
The thesis utilized on geometry optics and diffract optics to build the simulation system. First of all, the thesis introduces both the principles of the optical system and electro-optical signals in the optical storage system and also introduces the servo control of the system. Then, the architecture of the simulation system is illustrated to explain how to set up simulation system. The simulation system develops a DVD system firstly and successfully establishes the optical model and then simulates focus error signals (FES), radio frequency signal (RFS) and tracking error signals (TES). The result would be compared with the signals from the hardware in DVD to verify its accuracy. The simulation results also consider the influence of disc tilt and discuss the phenomenon as how they will affect the electro-optical signals. Then, the dynamic behavior of disc based on tracking error signals is added into the simulation and shows the influence of the disc eccentricity and disc tilt on tracking error signals. Finally, the simulation system takes tilt control into account to correct the influence which results from the disc tilt.
The simulation system can provide reliable information, and therefore the designers can depend on the simulation system to design system before the researchers can start designing the hardware system.
