完整的米勒矩阵的英国橡树（栎属robur）叶为一个固定的方位角（90度）后立即采摘和一天后暴露于正常的室温和压力。在0度至24度的观察角范围内对透射光确定Mueller矩阵，并且在153度至170度的反射后向散射角范围内对反射光确定Mueller矩阵。所有的测量都是用0.63微米的He-Ne激光光源进行的。由于相干矩阵的本征值是正的，因此偏振测量在物理上是可实现的。利用琼斯矩阵的分解定理，确定了各向异性参数。从M33和M44组件的穆勒矩阵，它被发现，非球形结构内的叶主要负责观察到的透射光散射，和球形结构主要负责观察到的后向散射。后向散射Mueller矩阵元素的变化，从一个新鲜的叶子到第二天的观察，因为叶片中的水蒸气浓度的变化被假定。
The complete Mueller matrix for an English oak (Quercus robur) leaf for a fixed azimuth angle (90 degrees) was determined immediately after plucking and a day following exposure to normal room temperature and pressures. The Mueller matrices were determined for transmitted light at observation angles ranging from 0 degrees to 24 degrees and for reflected backscattering angles from 153 degrees to 170 degrees. All the measurements were taken with a He-Ne laser light source at 0.63 microm. Since positive eigenvalues were obtained for the coherence matrix, the polarimetric measurements were physically realizable. The anisotropy parameters were determined from the Jones matrices by use of the decomposition theorem. From the M33 and M44 components of the Mueller matrices, it was found that nonspherical structures within the leaf were primarily responsible for observed transmitted light scatter, and spherical structures were mostly responsible for observed backscatter. Variations in backscatter Mueller matrix elements from a fresh leaf to a second day of observation were assumed because of changes to water vapor concentration in the leaf.
