Fraunhofer Diffraction from Sector Stars |
|
| Abstract: | The wavefunction of the Fraunhofer diffraction from sector stars (i.e. radial gratings, spoke targets, Jewell's tests, Siemens' stars) is derived. Particular features of the diffraction patterns are explained by means of both the derived mathematical formulae and the general properties of Fraunhofer diffraction patterns. The graphs and patterns of the sector stars with the symmetry n = 1, 2, 3, 4, 6 and 72 are given. |
