A systematic series of silicon (Si) wafer with microstructured anti-reflection film is prepared by femtosecond laser pulse. The dependence of the morphology and optical properties of the microstructured Si on the experimental parameters is thoroughly inve
本文描述了一个单频钕玻璃激光器,它采用脉冲透射式Q开关和腔反射镜选模技术,获得了脉宽5ns,能量0.5mJ的单模激光脉冲.同时测量了其输出激光的空间、时间和光谱特性,其实验结果与最佳耦合Q开关激光理论的预测值一致.
A calibration method for the five essential parameters is proposed. Using the calibration results, the three dimensional (3D) reconstruction can be performed directly. The five essential parameters include the distance between the camera and the projector

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
Quadrature imbalance compensation algorithm based on statistical properties of signals in CO-QPSK sy
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
