Abstract

The weighted-ordinate method of colorimetry is applied to Fresnel diffraction of white light by a circular aperture to determine the dominant wavelength, purity, and relative luminance of the center of the diffraction pattern. This chromaticity information is compared to experimental results and graphs are included to allow easy determination of these quantities for most combinations of aperture radius, source distance, and observation distance that would be of interest.
