WebJan 13, 2024 · This angle is also commonly known as the diffraction limit. Figure 14.6.2: (a) Graph of intensity of the diffraction pattern for a circular aperture. Note that, similar to a single slit, the central maximum is wider and brighter than those to the sides. (b) Two point objects produce overlapping diffraction patterns. WebA start has also been made on the more complicated problem of multiple apertures by computing the form of the far-field diffraction pattern of two adjacent semicircular apertures, over which the amplitudes and phases are constant in the two apertures, but the amplitudes in the two apertures have been assumed to be equal and the phases different.
