光线追迹 Trace of Light

程序目标

1. 计算单色光场在焦点附近的演化情况
2. 计算多色光场在有像差的情况下的烟花情况，并且比较最佳焦点与几何焦点处的成像质量差异
3. 计算脉冲光线的传播情况

Program Objectives

1. Calculate the evolution of a monochromatic light field near the focal point.
2. Calculate the “fireworks” phenomenon in a polychromatic light field under aberrations, and compare the imaging quality difference between the optimal focus and the geometric focus.
3. Calculate the propagation of pulsed light.
