论文摘要
对于给定的ASPHERE，光栅方程用于得出计算机生成的全息图（CGH）的设计，有时称为衍射无效校正器。 CGH将球形波转换为干涉测量学所需的适合给定的沥青的形状。该推导有效地分析，但在某些情况下可能需要数值实现，具体取决于沥青的形状和所需的准确性。
For a given asphere the grating equation is used to derive the design for a Computer Generated Hologram (CGH), sometimes referred to as a diffractive null corrector. The CGH converts a spherical wavefront to the shape appropriate for the given asphere as required for interferometric metrology. The derivation is effectively analytic but may require numerical implementation in certain cases depending on the complexity of the shape of the asphere and the accuracy required.
