matlab模拟几何光线追迹，计算双胶合透镜的像差(simulate the geometric ray tracing and calculate the aberration of double with matlab)

Design grating and simulate its diffracted orders with distortion. It can be used to design the dots-pattern illumination for structured-light 3D detection. 用于光栅设计和仿真其衍射级次的畸变效果。该程序能够用于设计点阵形式的结构光照明，以进行3D结构光测量。
