✦ Synopsis

The generalized diffraction integral formula for the misaligned optical system is simply described in Section 2. Based on the fact that a hard-edge aperture function can be expanded by an approximate sum of complex Gaussian function with finite numbers, the approximate analytical expression of its relative phase shift is derived in Section 3. And some numerical simulations are done in Section 4 to illustrate the dependence of the relative phase shift on the off-axial beam parameters, the aperture size and the misaligned parameter. At last, a simple conclusion is outlined in Section 5.
