本文所述反射棱镜系统泛指一切由平面镜和反射棱镜组成的光学系统。理论上可抽象为空间向量等模传输网络,物向量即网络的输入,象向量即网络的输出。物与象的共轭关系,如同共轴球面系统一样,可导出一般性解析模型,定量地用成象作用矩阵来描述。当网络的输入受到扰动(原始误差)时,网络的输出亦产生相应的扰动(输出误差)。这种误差传递关系是三维的,可定量地用网络的误差传递矩阵来描述。本文主要论述推导过程,不涉及具体应用。
Reflective prism system described in this article refers to all the optical system consisting of a flat mirror and a reflective prism. In theory, it can be abstracted as a modal transmission network such as space vector. The object vector is the input of the network, and the vector of vectors is the output of the network. The conjugate relation of objects and objects, like the coaxial spherical system, leads to a general analytical model that is quantitatively described by the matrix of imaging effects. When the network input is disturbed (original error), the network output also produce the corresponding disturbance (output error). This error transfer relationship is three-dimensional and can be quantitatively described by the network error transfer matrix. This article mainly discusses the derivation process, does not involve the specific application.
