bias testing

Application on digital image technology in decentration measuring for objective lens
数字图像技术在中心偏测试仪中的应用
The infrared results showed that the ir characteristic value l080cm - lof cubic crystal sio , and the absorption peak 460cm - l of mgf , caused by the interaction between f - - mg ' + - p elastic vibration and photon radiation , appeared in the ir spectra . ellipsometric analysis showed that the typical absorption peaks 58lnm , 589nm and 606nm , resulting from the surface plasma resonance of cu panicles and reflecting the absorption on composite film system , appeared in the extinction coefficient k curves of cu ( voll5 % ) mgf , , cu ( vol20 % ) mgf , and cu ( vol30 % ) mgf , cermet films , respectively . with the component of cu increasing , the peak site presented red shift , which was in accordance to the results of ultraviolet - visible spectra
椭偏测试分析表明： cu ( vol15 ) mgf _ 2 、 cu ( vol20 ) mgf _ 2和cu ( vol30 ) mgf _ 2样品的消光系数k曲线中出现了反映复合金属陶瓷体系吸收的由cu金属颗粒表面等离子体共振引起的吸收峰，峰位分别为581nm 、 589nm和606nm ，呈现红移，这些与紫外-可见光谱测试结果相一致；此外， cu - mgf _ 2复合纳米金属陶瓷薄膜光学常数的实验值与考虑尺寸效应修正过的mg理论值总体上符合得很好。
