Diffraction Effects on Broadband Radiation: Formulation for Computing Total Irradiance

Abstract
We present a formulation for treating diffraction effects on total irradiance in the case of a Planck source, whereas earlier work generally depended on calculating diffraction effects on spectral irradiance followed by summation over spectral components. The formulation is derived and demonstrated for Fraunhofer diffraction by circular apertures, rectangular apertures and slits, and Fresnel diffraction by straight edges and circular apertures. The prospects for treating other sources and optical systems are also discussed.
