Abstract:
A method and device for imaging an object illuminated by an X-ray beam, through a zone plate, is disclosed. A concave mirror with a multilayered film is disposed on a path of the X-ray beam to reflect the same and collect the same onto the object.
Abstract:
An X-ray multilayer film reflecting mirror comprises a plurality of substance layers formed on a substrate to be applied to X-rays having a wavelength of 100 .ANG. or less so that a deviation .DELTA. of the film thickness of each layer from a standard value is within a range defined by ##EQU1## where .theta. is the grazing angle of an X-ray being incident and .lambda. is the wavelength of the X-ray. Thus, the multilayer film reflecting mirror having the reflectance which is advantageous in practical use can be stably provided, and a product yield is improved.
Abstract:
A multilayer x-ray reflector or reflectors are used with a source of radiation for narrow bandwidth or dual energy radiographic imaging applications. In one aspect, a unique multilayer design permits two distinct x-ray energies of narrow bandwidth to be reflected at the same incident angle for use in dual energy applications. In another aspect, several multilayer reflectors are employed in a slit scanning system. In yet another aspect, an elongated radiation source and a multilayer x-ray reflecting structure are combined to provide an x-ray or gamma ray source.

Abstract:
Point source X-ray focusing device structures, materials and methods of forming them are provided which exhibit a greatly increased total reflected intensity for a desired X-ray wavelength of interest. The devices include one or more focusing elements which each have a focusing surface with a plurality of layer pairs formed thereon. The focusing surface and the layer pairs are designed to collect, reflect and concentrate the maximum X-ray flux from a point source to a focus point for a particular wavelength of interest.

Abstract:
One problem of projection optics concerns pupil apodization which leads to imaging defects. As here proposed, the illumination system is configured to illuminate the mask inhomogeneously. As a result, inhomogeneities in reflectivity caused by the mask itself are at least partly counteracted. This compensation not only makes the apodization over the pupil become more symmetric but also makes the intensity variation smaller overall.
