Web22 dec. 2024 · 衍射（diffraction）是指波遇到障碍物时偏离原来直线传播的物理现象。 波面的任何变形（通过相位物体）或者说波面（波前）上光场的复振幅分布受到任何空间调制，都将导致衍射现象的发生，而使通过障碍物以后的光场的复振幅重新分布。 WebThe Helmholtz–Kirchhoff diffraction integral expresses the disturbance at a given point in terms of its values and the values of its first derivative on the surrounding volumesA, B and C.In Equation (B.20), U is the disturbance to be determined andG¼(exp(jks))/s is the auxiliary Green’s function.
