| 摘 要： | 棱镜成像是静态问题，转动棱镜的成像方位变化属动态问题。反射棱镜绕某轴旋转，其特征方向就绕同一根轴转至新的方位，利用与的简单关系，比较特征方向处于新、旧两种方位时的棱镜成像，同时得到了棱镜调整计算的显式简单公式和“棱镜转动定理”。

| Abstract: | The image formation for a reflecting prism is a static problem, but the image orientation change caused by a rotation of a prism belongs to a dynamic problem. While a reflecting prism rotating about an axis P,the characteristic orientation T of foe prism rotates to a new orientation about the same axis.Comparing the image formation while is in the new orientation with the image formation while is in the original otientation and using the simple relationship between and,the simple and eXPlicit formulas for the prism's adjustment calculating are derived and the theorem of small rotation of a reflecting prism is proved at the same time. |
