The paper presents the experiment equipment for the measurement of the elastic-optic effect of curled birefringence fiber, then analyzes spectrogram at winding loss, and the rule of the circle of optical fiber producing elastic-optic effect. - 文中研究了极化雷达波在磁化等离子体中传播时的法拉第旋转、双折射等现象,分析了这些效应使雷达波产生极化损耗的机理。
This paper studies some phenomena accured when wave propagates in magnetized plasma such as Faraday-rotation, Dual-refraction, and analyzes the effect of plasma stealth technique on polarization loss. - 文摘:通过对光折变晶体的热透镜效应的理论分析发现,光通过光折变晶体时,只有在晶体发生双折射的前提下,才能发生热透镜效应.并指出,晶体内存在的由热效应引起的横向各向异性温度梯度仅是产生热透镜效应的一个方面,而“光阻”则是产生光折变晶体热透镜效应的另一个原因,从而丰富了光折变效应的内涵.
Abstract: It is found through theoretical analysis that,heat-lens effect arises only when the light is birefracted in photorefractive crystals.It is also point out that the lateral anisotropic temperature gradient is only one cause causing the heat-lens effect ,another is light-damper.
