将光栅系统的像差理论从一维扩展源扩展到二维扩展源。在推导像差公式时，应用子午面光瞳与矢状面光瞳分离的概念，并通过线性方程确定主光线。参考赛德尔像差，根据几何特征将像差分为七类。利用像差公式和精确光线追迹对一模型光学系统成像进行数值模拟，检验像差公式的准确性。
The aberration theory of grating systems is extended from one-dimension to two-dimension extended source. In deriving the aberration formulae, the concept that pupil in the meridional plane is separate from the one in the sagittal plane is applied and the principal ray is determined by a linear equation. Using the Seidel aberration for reference, the aberrations are classified into seven types according to the geometrical characteristics. The numerical simulation of imaging of one model optical systems is made with the aberration formulae and exact ray tracing to examine the accuracy of the aberration formulae.
