折射光学的

However,in practice, the excursion ,transmission refraction and optics aberrance of the laser beam will affect the measuring precision.

但在实际应用中，激光光束的漂移、传输折射以及光学畸变对测量系统的测量精度具有不可忽视的影响。

Not only the thermal properties but also the optical properties of these birefringent crystals are anisotropic.

这些双折射晶体不但光学性质是各向异性的，而且热学性质也是各向异性的，显然温度对这类器件性能的影响更是复杂，也更是不客被忽视的。

Currently in initial production, the Off-Axis Viewing Deviceis a small viewing unit that mates with a weapon′s existing receive-mounted optical sight and provides an image of the target transmitted through the scope and reflected 50°to the line-of-sight back to the firer.

目前，初期生产的离轴式观察装置是一种与装在支座上的光学瞄准具相配的小型观察器，它能将透过物镜的目标图像折射50°到视线方向，再提供给射手。

We stress, however, that the material birefringence is not really important in our experiment, and that the same apparatus could be used, in principle, to optically manipulate isotropic transparent bodies also.

然而，我们强调，在我们的实验中，双折射材料并不是真正很重要的，在原理上，同样的仪器也可用于光学操纵各向同性透明介质。

Here in our department, the Geometric-Optics is a 3-credit, 3-hour per week, one-semester course. There are three consecutives parts in the one-semester lecture:The 1st part :the nature of light,the related theorems about reflection and refraction, image formation.

本系之几何光学是一学期、三学分、每周三小时的课程，教学内容大致包含以下三部份：一、介绍光的性质、在介面上反射、折射之有关定理、成像的原因及应用。

The effects of the central wavelength shift of the source and the variations of the parameters of the sensing head (Verdet constant and linear birefringence) due to ambient temperature fluctuation upon the scale factor of a bulk-glass optical current transformer are theoretically analyzed and digitally simulated.

用理论分析和计算机仿真的方法研究了环境温度变化导致的光源中心波长移动和传感头材料Verdet常量与应力双折射变化对光学电流互感器输出性能的影响。

The time-resolved hemispherical reflectance and transmittance of the slabs with linearly varying refractive index are obtained for various optical thicknesses, scattering albedos and substrate reflectances.

接著，求各种光学厚度、散射比和基底反射率的线性可变折射系数平板的时间分解半球反射率与半球穿透率。

An optical illusion in which atmospheric refraction by a layer of hot air distorts or inverts reflections of distant objects.

一种光学错觉，大气中的一层热空气通过折射扭曲或颠倒了远处物体的影像。

The solar halo is one kind of optical phenomenon which results from the small drops of water in cirrus and cirrostratus formed the larger sparkling and crystal-clear ice when they run into the cold air.

日晕，是一种光学现象，是因为天空卷云和卷层云中的小水滴凝结成颗粒较大的冰晶，而冰晶对阳光进行折射和反射，把阳光分解成了红、黄、绿、紫等多种颜色的结果。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
