发生在时变系统中所展示的频谱扩展。待仿真系统是一个简单系统，其中系统的代桶输入是一个形为x(t)=cos[2π(f0+f1)t]的“音频”。(Occurred in the time-varying system in spread spectrum display. Subject to the simulation system is a simple system in which the generation of the system input is a bucket-shaped to x (t) = cos [2π (f0+f1) t] of the " audio." )

本程序基于Matlab，可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光，点光源任意角度光线，并对全反射，光线射出系统等特殊情况用红色标出。透镜数任意，透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)
