Abstract
We present a scheme which combines focusing of atomic de Broglie waves by s tanding light waves and fractional Talbot imaging to produce nanostructures . Masking of the incoming atomic wave by an absorptive grating is used to e liminate atom-optical aberrations that would otherwise wash out the fractio nal Talbot images. The scheme allows the creation of structures of very sma ll feature size as well as small period.
