引入二元衍射模型，研究了二元计算全息图的波前相位对槽深和占空比变化的敏感性。衍射效率，衍射波前相位函数，波前灵敏度函数的解析解。这些关系的推导是通过使用傅立叶方法获得的。实验数据的结果证实了分析。几个相位异常被发现，和一个简单的图形模型的复杂的字段被应用到解释这些现象。
A binary diffraction model is introduced to study the sensitivity of the wavefront phase of binary computer-generated holograms on groove depth and duty-cycle variations. Analytical solutions to diffraction efficiency, diffracted wavefront phase functions, and wavefront sensitivity functions are derived. The derivation of these relationships is obtained by using the Fourier method. Results from experimental data confirm the analysis. Several phase anomalies were discovered, and a simple graphical model of the complex fields is applied to explain these phenomena.
