隨著通訊資料高速度需求的增加，光通訊技術更顯重要; 高功率980-nm雷射應用於遠距離傳輸時，作為光訊號放大的能量來源，而四角錐光纖鏡面是用於980-nm高功率雷射與單模光纖間耦光的鏡面，在此研究中完成建構一套利用CCD( Couple Charge Device )做為位置感知器的線上檢測系統，此系統已成功的使用在裸光纖研磨機上，檢測光纖在研磨期間的研磨量，因此本研究將會是朝向自動化光纖研磨系統的重要技術之一。

For the requirements of high-speed signal transmission has been increasing. Optical communication system is the way to solve the demands. The 980-nm high-power laser modules are used for optical communication system as the power of the amplifier for long distance communication. The QPSFE is used for coupling between the high-power 980nm laser diodes and the single mode fiber. This research established an on-line inspection system to inspect the fiber endface during the polishing process which is applied on a bare fiber polishing machine. The system we developed is to detect the fiber endface for QPSFE fabrication process. In this paper, we simply use couple charge device (CCD) as a position sensor to detect the grinding situation. The system had been successfully achieved on-inspection purpose, therefore; it will be the key technique toward the automatic bare fiber polishing system.
