The geometric theory of aspheric wave-front recording optics is extended to include the fourth-order groove parameters that correspond to the fourth-order holographic terms in the light-path function. We derived explicit expressions of the groove parameters by analytically following an exact ray-tracing procedure for a double-element optical system that consists of a point source, an ellipsoidal mirror, and an ellipsoidal grating blank. Design examples of holographic gratings for an in-plane Eagle-type vacuum-UV monochromator are given to demonstrate the capability of the present theory in the design of aspheric wave-front recording optics.
非球面波前记录光学的几何理论得到扩展，以纳入与光程函数中的四阶全息项相对应的四阶沟槽参数。我们通过对由点光源、椭球面镜和椭球面光栅坯料组成的双元件光学系统进行精确光线追迹程序，解析推导了沟槽参数的显式表达式。给出了用于面内鹰式真空紫外单色仪的全息光栅设计示例，以证明本理论在非球面波前记录光学设计中的能力。
