Abstract

An X-ray interferometer can be realised using a simple geometric arrangement of flat grazing incidence mirrors and a slatted grazing incidence mirror. This optical design has the advantage that large baseline separations ~ 1m can be accomodated within an envelope 2m by 20m. Operating at 1 keV such a device could provide angular resolutions of 100 micro arc seconds with a collecting area large enough to allow imaging of many potential astronomical targets. We describe the construction of an Optical Demonstration Model, working in the visible band, used as a proof of concept for the proposed scheme.
