A Large-Aperture High-Accuracy Lateral Shearing Interferometer for Flow Visualization

本文介绍了一种新型大口径、高精度横向错位干涉仪的工作原理。

This paper presents the principle of a new large-aperture high-accuracy lateral shearing interferometer .

透镜耦合器的耦合系数对横向错位十分敏感，因而容易受震动等环境条件的影响。

The coupling efficiency of a lens coupler is highly sensitive to the lateral disalignment and may be affected by the environment condition such as vibration .

第二位的或低下的位置。建议低速磁浮车辆采用磁铁横向错位布置和横向位移与速度反馈主动导向方式。

It is suggested that the low-speed maglev vehicle should adopt the lateral-offset magnets and the active guidance mode using the lateral displacement and velocity feedback .

本文对光纤连接时的横向错位损耗进行了仿真分析，利用损耗与错位量之间的关系，可以设计出结构简单，回波损耗较高的光衰减器。

Transverse displacement loss of fiber connection is analyzed in this paper . A kind of optical attenuator can be designed using the relation between loss and displacement which has simple structure and high return loss .

分析光纤双法-珀干涉仪腔镜的倾斜角对干涉条纹的影响，腔镜横向错位以及倾角引起的光强损耗等。

This paper presents the analysis of the effects of the tilt angle of the F-P cavity mirror on the interference fringes and the optical loss caused by the cross malposition and the tilt angle of the cavity mirror .

最后，应用数值计算得到模式噪声信噪比与接头横向错位程度、相干性消失度、接头前光纤长度等关系曲线，结果与实验定性相符。

Finally , it gives , by curves obtained by numerical calculation , the relations between SNR of modal noise and the degree of transversal misalignment , degree of incoherence and fiber length before joint , And the results agree qualitatively with that obtained by experiments .
