提出了一种对望远镜焦平面中的仪器偏振进行建模的技术。它考虑到入射光束的不同光线在通过系统的路径中会遭受原始偏振的不同变化。它还认为净效应取决于不同光线相互干扰的方式。结果表明，如果偏振测量的空间分辨率较差，则描述仪器偏振的穆勒矩阵会大大简化
A technique to model the instrumental polarization in the focal plane of a telescope is presented. It takes into account that different rays of an incoming beam suffer different variation of the original polarization in their paths through the system. It also considers that the net effect depends on the way in which the different rays interfere with each other. It is shown that the Mueller matrix which describes this instrumental polarization greatly simplifies if the polarimetric measurements have poor spatial resolution
