Kirchhoff diffraction

Web15 dec. 2007 · In scalar diffraction theory, Kirchhoff formula, Rayleigh–Sommerfeld formula, and angular spectrum transmission formula are classic formulas that express diffraction correctly. But as complex calculation, Fresnel diffraction integral, which is the paraxial approximate solution to these formulas, is used widely. WebKirchhoff’s diffraction theory, which is often criticized because of an apparent internal inconsistency, is shown to be a rigorous solution to a certain boundary-value problem …

WebThe diffraction formula is based on scalar diffraction theory, which ignores polarization effects. In some situations, ignor-ing polarization is benign, but in other situations, ignoring polarization effects produces significant errors. These issues as well as the approximations leading to scalar diffraction theory are discussed in section10.2.
