首先,利用透明物体表面反射光和透射光在垂直和平行方向上的光强分布关系,基于偏振正交分解原理,推导出反射光成分、透射光成分、反射光偏振度、透射光偏振度之间的函数关系。然后,根据相机成像原理,利用表面法向量求解得到透明物体表面不同位置处入射光线和法向量的夹角及入射面方位角,进而归纳出图像中各个像素点的反射光偏振度和透射光偏振度的分布规律。最后,基于反射和透射的偏振特性和相关特性,利用梯度下降算法计算得到反射分量和透射分量之间归一化的互相关最小值,最终实现反射光和透射光的分离,进而抑制了透明物体表面反射光

We propose a type of diffractive optical element, a modified Fibonacci photon sieve (MFiPS), designed by using the Fibonacci sequence with two different initial seed elements. Focusing properties of MFiPS show that it not only has less secondary foci, but
