    Abstract: 依照工業界對量測光束寬度所訂定之規範及方法進行研究,並以ISO 11146的標準來實施。工業界常用測量的方法有四種,如以照相機為基礎(Camera-based)之量測系統,狹縫(Slit)掃描器,刀邊(Knife-edge)掃描器,針孔(Pinhole)掃描器等。Camera-based 量測系統是以電荷偶合元件(Charge Couple Device, CCD)或互補金屬氧化半導體(Complementary Metal Oxide Semiconductor, CMOS)對光束進行分析,如光束強度過強則必須加裝衰減片進行保護,否則對CCD或CMOS元件會造成傷害,之後可找出光束的大小及照度的強弱;而後面三種則是以測量儀或者是光功率計架在螺旋測微移上,而且接收面必須與光束垂直,以數μm的間距進行步進量測,再依工業標準所規定的,以測量到最大功率的1/e2(13.5%)之處為光束的寬度大小。期許透過本研究,能夠幫助業界在制定精密光學機台上,對光束寬度的允收標準及日後的維護調校,有具體的方法與技術可參考。
