Moreover , compensated for aberration of ball lens by designing phase compensating plate to get a higher energy utilization rate . third , combining with the light beam property of dwdm system , put forward taking fresnel lens array as fiber arrayed collimator , designed differently structured lens array and discovered the arrayed collimator loss property , which compared with the existing parameter of fiber collimator , embodies many advantages as arrayed collimator 結(jié)合密集波分復(fù)用系統(tǒng)的光束耦合特點(diǎn),提出用菲涅爾透鏡列陣做光纖陣列準(zhǔn)直器,并設(shè)計(jì)不同結(jié)構(gòu)的透鏡列陣,得出了該陣列準(zhǔn)直器的光束耦合損耗特征,與現(xiàn)有的光纖準(zhǔn)直器的參數(shù)相比,體現(xiàn)出用菲涅爾透鏡列陣作陣列光纖準(zhǔn)直器的諸多優(yōu)勢(shì)。
