Abstract
THE expression of the electron density in a crystal as a Fourier series is the mathematical equivalent of the process of image formation by light waves in an optical instrument. Thus, if the X-ray diffraction data can be converted into appropriate light waves, it should be possible to produce an image of a crystal optically instead of by the more arduous process of calculation. Making use of this idea, Bragg1 produced an image of the projection of the crystal diopside, CaMg(SiO3)2, on the (010) plane.
