Matlab实现光线跟踪算法，建模光线折射、衰减、像差-Matlab to achieve ray tracing algorithm, modeling of light refraction, attenuation, aberrations

这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for

细丝直径的高精度测量是工业生产中的实际问题，如漆包线生产厂家需测量外围绝缘漆的厚度，要求精度达到微米量级。传统的接触式方法无法达到，采用激光衍射的方法，利用工业相机接收衍射图案，并结合图像处理计算可计算出激光衍射极小值点的间距，进而根据理论计算出待测细丝的直径。(Determination of incidence and refraction of light and its range)

基于MATLAB软件，使用者在交互界面GUI上输入入射介质、反射介质的折射系数n1、n2，可算得不同入射角条件下线偏光/自然光的菲涅尔透反射系数及透反射比(Based on the MATLAB software, the user can input the refraction coefficients N1 and N2 of the incident medium and the reflecting medium on the GUI of the interactive interf
