A light ray, incident at about 5 degrees to the normal, is geometrically plotted through the drawing of the cross section of a soybean leaf using Fresnel's equations and Snell's law. The optical mediums of the leaf considered for ray tracing are air, cell sap, chloroplast, and cell wall. The above ray is also drawn through the same leaf cross section considering cell wall and air as the only optical mediums. The values of the reflection and transmission found from ray tracing agree closely with the experimental results obtained using a Beckman DK-2A spectroreflectometer.
一束与法线成约5度角入射的光线，通过使用菲涅尔方程和斯涅尔定律绘制大豆叶片的横截面图，从几何角度进行了绘制。在光线追踪中考虑的叶片光学介质有空气、细胞液、叶绿体和细胞壁。上述光线也通过将细胞壁和空气作为唯一光学介质的同一叶片横截面进行绘制。从光线追踪中得到的反射和透射值与使用贝克曼DK - 2A光谱反射仪获得的实验结果非常吻合。
