提出从接收到的光信号脉冲串中提取光基频时钟的方案。此方案的要点是:首先在光脉冲的复用过程中人为地使复用后相邻码的时间间隔不相等,即复用为非均匀码。其次,在接收端利用光纤环形锁模激光器提取与复用前原信号同频率的时钟脉冲。实验的初步结果及理论分析表明所提出的时钟提取方案是可行的。
A novel laser-electro magnetic acoustic transducer (EMAT) system for nondestructive testing NDT surface crack of continuous casting billet (CCB) is provided. Rayleigh wave generated by line laser source is used to detect the surface crack of CCB. Accordin

由于液晶显示器不能完全满足通道独立性和色品恒定性而导致其色度特征化精度不高,故液晶显示器精确色度特征化模型的研究具有重要意义。将分空间处理的思想应用于对液晶显示器色度特征化精度较高的掩模(Masking)模型,提出了分空间补偿(SC)模型。该模型将RGB颜色空间分为8个子空间,基于不同子空间的相应训练样本,将掩模模型的预测三刺激值差值拟合成各通道驱动值的多项式函数,并对其三刺激值进行补偿。通过对四台液晶显示器色度特征化的实验测试表明,分空间补偿模型的最优平均预测色差分别为0.2783,0.3199,0.7
In this paper, high-speed surface-illuminated Ge-on-Si pin photodiodes with improved efficiency are demonstrated. With photon-trapping microhole features, the external quantum efficiency (EQE) of the Ge-on-Si pin diode is
测量了SrTiO3:Cr3 晶体5~200K的荧光光谱和寿命。并用单声子吸收与发射过程相关的电子振动跃迁理论较好地解释了150K以下荧光寿命随温度变化的规律。

Precisely distinguishing between hyperplastic and adenomatous polyps and normal human colonic mucosa at the cellular level is of great medical significance. In this work, multiphoton laser scanning microscopy (MPLSM) was used to obtain the high-contrast i
Highly conducting ZnO:Al (AZO) films are normally prepared through substrate heating and post-annealing in reducing atmosphere, which is deleterious to maintain the high transparency of films and the overall so-lar cell performance. Here we fabricate AZO
To increase the photoelectronic conversion efficiency of the single discharge tube and to meet the requirements of the laser cutting system, optimization of the discharge tube structure and gas flow field is necessary. We present a computational fluid dyn
