The use of a compact disk (CD) pickup head as a displacement measurement system is described. The components contained in a pickup head are explained and how they are combined to obtain the functionality of a pickup head. The application of measuring a kn
We propose a blind quadrature imbalance (QI) compensation algorithm based on the statistical properties of I and Q signals in a receiver. The algorithm estimates the QI parameters of a receiver by calculating the mean, variance, and correlation coefficien
A diffusion theory model induced by a line source distribution is presented for oblique-incidence reflectometry. By fitting to this asymmetric diffusion model, the absorption and reduced scattering coefficients \mu_a and μ^'_s of the turbid medium can b
The Erasmus Plus programme ‘Innovative Education and Training in high power laser plasmas’, otherwise known as PowerLaPs, is described. The PowerLaPs programme employs an innovative paradigm in that it is a multi-centre programme where teaching takes plac
FY-3B中分辨率光谱成像仪(MERSI)不能实现可见光近红外波段的星上绝对定标。为了提高MERSI高信噪比窄波段通道的辐射定标精度,针对国际通用的6个北非沙漠目标,利用高质量的SeaWiFS数据构建天顶双向反射分布函数(BRDF)模型,借助MODTRAN辐射传输模型和ERA-Interim再分析资料吸收气体数据构建光谱匹配因子,对FY-3B MERSI 5年的在轨运行数据进行交叉定标研究。所构建
用MeF3金相显微镜观察了多畴和单畴的LiNbO3晶体的X、Y、Z切面的蚀像和光像.发现各切面光像形态与各切面的蚀像形态对应,并与晶体的对称性完全一致.利用晶体的光像确定晶体极性和晶轴是一种简便的光学方法.
采用微波法合成银纳米颗粒,通过化学自组装技术将银纳米颗粒吸附在玻璃基片上, 制备了银纳米颗粒的局域表面等 离子体传感器。在纯水中,紫外可见光消光谱表明局域表面等离子体共振位于428 nm处。随外界折射率增加,共振峰发生红移,其 折射率灵敏度达到(173±6) nm/RIU。在350 ℃温度下退火处理后,改变银颗粒在基片上的形貌,峰位发生约65 nm的红移,灵敏度 下降约20%。理论分析表明,银纳米颗粒形状和基底的相互作用影响折射率传感的波长响应和灵敏度特性。
