laser optics

According to the basic traditional theory of laser optics and the novel properties of negative-index material, the theory model for paraxial Gaussian beams in the NIM is obtained from the Maxwell equations.

利用传统激光光学的基本原理，结合负折射率材料的新特性，从Maxwell方程组出发，建立负折射率材料中傍轴高斯光束传输的理论模型。

激光测距系统实现测距功能：激光发射光学系统发出的激光由激光接收光学系统接收，通过程序用于激光测距，测距数值同样显示在液晶板并通过左目镜观察。

It is well known that there is apparent inconsistence or paradox in the conventional theory of laser optics due to the assumed paraxial approximation or assumption of slowly varying amplitude.

众所周知，传统激光光学理论，由于采用了傍轴近似或缓变振幅近似，存在明显的不自洽性和佯谬；
