Abstract : The diffraction of coherent light by two circular apertures arranged in the shape of a 'Figure 8' is considered. The far-field or focal plane irradiance patterns are calculated and integrated over circular areas. The results are displayed in graphical form using dimensionless coordinates which are functions of the aperture size as well as the amplitude and phase distortions present in the radiation illuminating the aperture. Five cases which represent physically meaningful amplitude and phase profiles in the illuminating light are treated analytically. (Author)
