Abstract : The diffraction of Gaussian light beams by circular apertures is considered. The far field or focal plane irradiance patterns are calculated and integrated over circular areas. The results of the irradiance integrations are displayed in graphical form using dimensionless coordinates. Using the Fresnel diffraction integral, it is analytically proved that the total beam power passing through the focal plane is exactly equal to the beam power transmitted by the aperture. (Author)
