The preliminary conclusion shows that the maximum rate of compression ratio changes is about 2 % and the change rate is less when the peak - to - valley value of wavefront aberration is less than a quarter of wavelength and incident angle is properly 脉冲压缩光栅对系统达到衍射极限时，在选择适当的入射角度时，光栅波像差所引起的脉冲压缩比变化并不大。
