Using the scalar diffraction theory, derive Fresnel-Huygens diffraction integra
which gives the field at point P on the observation plane due to diffraction of light from an aperture A.
The Fresnel-Huygens diffraction integral, based on scalar diffraction theory, describes the diffraction of a wavefront due to an aperture. The integral expression: \[ U(P) = \frac{iE_0}{\lambda} \iint_A \left(\frac{e^{ikr}}{r}\right) d\xi d\eta \] gives the field at a point \( P \) on the observation plane due to diffraction from an aperture \( A \). --- ### Derivation of the Fresnel-Huygens Diffraction Integral We _______ ________ ______ _______ _________ __________ ________ ______.
