dc.description.abstract光學量測技術目前被大量使用在科學研究、工業研發、量產製造及消費性產品上。光學量測技術的主要原理,為使用一光源投射在待測樣品上,待測樣品改變投射光源的光學特性,再由偵測器量出被樣品改變後散射或反射光的光學特性。藉由分析入射與出射光學特性改變,可以量測到待測樣品的特性。因此,檢測技術所使用之光源將影響最後檢測結果之訊噪比。 a. 熱光效應光錐濾波器:本論文組合錐形光纖及光學匹配液構成高斯濾波器,並且藉由熱光效應可以調整濾波器的通過頻帶。借由此濾波器可修正OCT的寬頻光源頻譜,並且得到高解析度的生物影像。 b. 超寬頻光源:本論文採用80fs的Ti:sapphire雷射注入錐形光纖中,產生400 nm到1200 nm的超寬頻光源。同時採用數值模擬進行超寬頻光源產生過程的動態模擬,探討注入脈衝初始啾頻如何影響超寬頻光源的產生。 c. 單一縱模雷射光源:單一縱模光纖雷射可被應用於光纖通訊、光纖感測器和光譜分析等領域。在此論文中採用雙共振環路限制縱模模態,由摻鉺波導放大器、兩路不等長共振環路及Fabry-Perot可調濾波器構成單一縱模光纖雷射。並且討論此雷射架構的輸出強度、側模抑制比、波長及輸出強度的穩定度。 d. 高動態範圍疊紋干涉術:本論文將提出一種利用面型感光元件(CCD或CMOS)做單次曝光(one-shot)可得到高動態範圍影像之技術。利用此技術可以得到大範圍且不損失影像細節之高動態影像資料,對此高動態影像進行後續處理,可提高量測之準確度。zh_TW
dc.description.abstractOptical measurement techniques have been receiving an increasing attention during recent decades. The most important reason is that they work non-intrusively and therefore do not influence the investigated process. The continuing developments in laser, detector, optical fiber and computer technology will further augment the high applicability and versatility of optical measuring techniques. Therefore, it can be expected that optical techniques will continue to gain in importance in many fields of application. However, the procedures of optical measurement techniques include emitted a light signal, this signal modulated by device under test and analyzed the difference of those signal. The purpose of this dissertation is to discuss what is important in optical measurement technology is to adjust the light source suited with this measurement.en_US
