本文用复四元数讨论三平面镜系在会聚光路的成象规律,它们或相当于空间的定点转动,或等效于一个特殊的平面镜,举出几个实例加以说明。
In this paper, the complex quaternion is used to discuss the imaging regularity of the converging optical path of the three-plane mirror system. They are either fixed-point rotation equivalent to space or equivalent to a special plane mirror. A few examples are given to illustrate this.
