| Claim | - 18 . (canceled) A method for X-ray illumination, comprising: providing a poly-energetic X-ray beam for illuminating an object to be imaged; reflecting a first portion of said poly-energetic X-ray beam, the first portion comprising X-rays that have energies less than a lower pass-band energy; transmitting a second portion of said poly-energetic X-ray beam attenuating said first portion of said poly-energetic X-ray beam; reflecting a third portion of said second portion of said poly-energetic X-ray beam, said third portion comprising X-rays that have energies less than an upper pass-band energy; attenuating a fourth portion of said second portion of said poly-energetic X-ray beam, the fourth portion comprising X-rays that are not reflected; and providing said third portion of said second portion of said poly-energetic X-ray beam to illuminate said object to be imaged, wherein said third portion comprises X-rays having energies between said upper pass-band energy and said lower pass-band energy. The method according to claim 19 , wherein said reflecting said first portion of said poly-energetic X-ray beam and said transmitting said second portion of said poly-energetic X-ray beam further comprises: directing said poly-energetic X-ray beam to be incident upon a membrane X-ray mirror comprising a reflecting layer that comprises a high-Z material on a support layer that comprises a low-Z material, wherein Z is an atomic number, wherein said high-Z material includes atomic elements with Z at least 42, and wherein said low-Z material includes atomic elements with Z less than 14. |
