31. In it he showed how to calculate the densities of diffracting materials from their X-ray diffraction patterns . 32. Their diffraction pattern would be of a square type with the intensities arranged in a fractal pattern. 33. This is the back focal plane of the microscope, and is where the diffraction pattern is formed. 34. The diffraction pattern of a crystal can be used to determine the reciprocal vectors of the lattice. 35. A diffraction pattern is obtained by measuring the intensity of scattered waves as a function of scattering angle. 36. The beam scattered by the object produces a diffraction pattern downstream which is then collected by a detector. 37. The observed diffraction pattern generally consists of two diffraction maxima; these are the zeroth and the first orders. 38. The diffraction pattern is still seen. 39. Advanced programs have been developed allowing one to construct, visualize and analyze quasicrystal structures and their diffraction patterns . 40. Pribram proposed that neural holograms were formed by the diffraction patterns of oscillating electric waves within the cortex.
