提高激光脉冲幅度稳定性的时空变换工作原理

用激光脉冲同步触发高压电脉冲发生器，驱动LiNbO3电光偏转器对激光脉冲进行快速偏转，当与高压电脉冲前沿同步的激光脉冲经过晶体时，不同时刻对激光脉冲产生不同的偏折而偏离原来的传播方向，偏转后的激光束在空间形成一扫描光线，实现激光脉冲的时空变换。用狭缝在扫描光线上的某一位置截取激光脉冲输出．经过时空变换后，提高了激光脉冲幅度稳定性．实验结果激光脉冲幅度稳定提高了约61．6％．且激光脉宽得到压缩。     

Free-Space Optical communication using visible light

INTRODUCTION A growing and seemingly insatiable bandwidth demand in the marketplace is bring Free-Space Op- tical (FSO) technology into the carrier space as a means of broadband access for closing the “last mile” connectivity gap throughout metropolitan networks. Terrestrial short-range FSO systems which are gen- erally point-to-point links between buildings on the campus or different buildings of a company can be used to setup wireless communication networks or to supplement radio a…

Proteiomic patterns for endometrial cancer using SELDI-TOF-MS

Serum samples from endometrial cancer (EC) patients and healthy females were analyzed using surface-enhanced laser desorption-ionization time-of-flight mass spectrometry (SELDI-TOF-MS) to discover the potential diagnostic biomarker for detection of EC. A preliminary training set of spectra derived from 40 EC patients and 30 healthy women were used to develop a proteomic model that effectively discriminated cancer patients from healthy women. The training set had a specificity of 100% and sensitivity of 92.5% in the EC detection. A blind test set, including 20 new cancer cases and 10 healthy women, was used to validate the sensitivity and specificity of this multivariate model, which had a corresponding results of 60% in specificity and 75% in sensitivity, respectively. The combination of SELDI-TOF-MS with bioinformatics tools could help find new biomarkers and establish the detection of EC with high sensitivity and specificity.     

利用三维激光扫描测量数据与电脑绘图软件绘制敦煌彩塑

作为文物的敦煌彩塑需要重点保护,不能随意触碰与移动,但其本身结构复杂,具有不规则性,且所处空间狭小,测绘难度较大。数字化是文物保护工作的重要内容与手段,如何利用数字化手段和成果精确绘制各种考古测绘图需要在实践中逐步探索。本文以莫高窟第275窟主尊(交脚菩萨)为例阐述了利用三维激光扫描测量手段,非接触式测量与三维复制敦煌彩塑,并利用三维点云数据精确绘制彩塑的图纸。
