Quasicrystal Diffraction Patterns
Fri, Apr 2, 2010
You're killing me. I have a feeling that I should have known that, but I am not sure even what you're talking about. They have a very small device mounted on the ceiling with the red and green laser. The output draws tens of dots on the ground. Usually they are in lines (rows, columns) with the big dot in the middle, and the progressively smaller dots to the sides. They are exactly like the laser beam exiting the micro-scale grating! Then again, would they really use the grating?? The crystals cannot diffract light like this as far as I know, they use X-rays to obtain the exact images that you showed.
I think that the Fourier analysis would show a graph of the frequencies of occurrences per length or angle of knots (or nodes) in the crystal.
