Abstract
Several Journal articles have described the Fourier method of x-ray crystallography, and the demonstration of using a small diffracting pattern to diffract the light from a low intensity laser beam is well known. It is much less well known that the diffracted light can be deconvoluted and projected to give an image of the diffracting pattern. This article describes illustrating such a Fourier transform.

George C. Lisensky , Dean J. Campbell , Katie J. Beckman , Camilo E. Calderon , Patrick W. Doolan , Rebecca M. Ottosen and Arthur B. EllisJournal of Chemical Education1999 76 (4), 537This paper describes simple classroom demonstrations and laboratory experiments based on properties of polydimethylsiloxane (PDMS). PDMS is a colorless, transparent elastomer. Spheres cast from PDMS can be cross-linked to varying extents to affect their ...
