摘要
根据光线追迹方程,利用MATLAB软件实现点光源到渐变折射率透镜(GRIN透镜),再到接收面的光线轨迹计算。该透镜的外观为规则圆柱,其内部折射率连续变化。用蒙特卡洛算法模拟LED朗伯点光源的出光特征;利用MATLAB软件对渐变折射率透镜中的光线进行光线追迹,观察LED光线穿过该透镜后在接收面上所呈的像;经过物理场仿真软件的仿真与验证,该算法的正确性与可靠性得到肯定。这些理论准备与工作为利用体透镜进行非成像光学设计提供了理论与实验基础。
Based on the ray tracing equation, the traces of lights are simulated with a MATLAB program. All the lights are emitted from a point source, passed through GRIN lens and hit on the target surface. The lens are cylindrical, whose in- ternal refractive index varies continuously. Simulate the Lambert LED pot light by Monte Carlo algorithm. Use MATLAB software to achieve light ray-tracing for the gradient index lens, then observe the image on receiver, which comes from LED rays through the lens to the receiving surface. The ray tracing method is verified by the simulation result from FEMLab software. These theoretical preparation and work proves a theoretical and experimental basis of the non-imaging optics lens design.
