While the new components having the same numbers with these original physical vectors are introduced and the new components are combined with those original physical components to form a new symplectic space, the ray problem of wave propagation in geometrical optics is converted into the problem of Lagrange submanifold in the symplectic space.

本论文的工作作为国家自然科学基金地震波传播与成像项目（NO.40174032）的一部分，得到如下结果：论文分析了利用Maslov方法求解非均匀介质中波动方程高频近似解的基本原理和求解过程，构造了介质系数只在一个方向变化时波动方程高频近似解的通用计算公式。

We are engaged in the work of the frequency and phase stabilization of the diode laser and its application in atomic optics on this background.

本文正是在这样的背景下，选择了半导体激光的稳频和稳相技术及其在原子光学中的应用作为研究课题。

Adaptive optics are being used widely in laser material processing technology.

在激光加工技术中，自适应光学元器件的应用越来越广。

He also independently discovered the law of reflection, and his essay on optics was the first published mention of this law.

他也独立发现了反射定律，他的光学论文是第一次公开发表提到此定律的论文。

Based on Fermat's theorem, the law of reflection and refraction is obtained, and the geometrical ray tracing method of reflected light is introduced. In response to geometric optics rainbow theory and Airy rainbow theory, the relationship formula of the N-order rainbow angle with the refraction index and the Airy peak value position formula are derived, and the physics causation of the first order rainbow are discussed and analyzed in detail. The distribution properties of the first and second order Airy structures of spherical particles are calculated.

利用费马原理推导了反射和折射定律，以反射射线的跟踪为例介绍了几何光学射线跟踪方法的推导过程；根据几何光学彩虹理论和Airy理论，推导了N阶几何光学彩虹角与入射角和折射率的关系及Airy峰的位置表达式，详细阐述了一阶彩虹形成的物理原因，计算了球形粒子的一、二阶Airy分布。

The mechanical measurement is to use an indicator to measure the surface or the edge of the testing lens mounted in a specific holder in a contact way. The principle of the optical measurement is the geometric optics, utilizing the properties of refraction or reflection of light to detect the centering error of the testing elements in a contactless way.

机械式的测量是利用指示器配合治具对待测透镜之外缘或表面进行接触式测量；而光学式的测量原理则是利用几何光学的折射或反射性质，对待测元件进行非接触式的偏心误差量测。

The concept of light ray is one which will be of sustained interest to us through our study of optics.
