The prism turning theorem as first put forward in China describes the directional conjugate relation between the object and the image space, being applicable to afocal systems.

棱镜转动定理是我国首先提出的，实际上此定理描述的是物、象空间方向共轭关系，适用于无光焦度光学系统。

This is a constant-amplitude wave which is essentially the same on the conjugate image plane.

这是一个振幅恒定的波，在共轭的象平面上也是如此。
