Abstract

Multi-element sensor arrays of low-r@7ectivi@c, hiTed, apodized, 1 cm long, and 1 nm wide gratings hove been fabricated inter$emmetrically. Once exposed, points along each grating ore re-illuminated with fringeless ullro-violet light to achieve < 1 %flat top ripple in reflectiviw and no sideband to -30 dE.

利用曝光后重新扫描技术为应变传感器阵列制造具有定制光谱特性的光纤光栅

采用几何方法制备了low-r@7ectivi@c、hiTed、apodized、1cm长、1nm宽光栅的多元件传感器阵列。一旦曝光，沿着每个光栅的点再次用无条纹的紫外光照射，以实现反射光< 1%的平顶纹波，并且没有边带到-30度。
