Fraunhofer Diffraction Effects on Total Power for a Planckian Source
Eric L. Shirley
An algorithm for computing diffractions effects on total power in the case of Fraunhofer diffraction by a circular lens or aperture is derived. The result for Fraunhofer diffraction of monochromatic radiation is well known, and this reports the result for radiation from a Planckian source. The result obtained is valid at all temperatures.
