Patent Number: 06041099&
Section: claims

1. An x-ray directing system comprising: a Kirkpatrick-Baez side-by-side optic which redirects x-rays, wherein said Kirkpatrick-Baez side-by-side optic has multi-layer Bragg x-ray reflective surfaces.  a unitary x-ray reflector having at least two reflective surfaces pre-aligned and bonded together;  wherein said x-ray reflector is a multi-layer Bragg x-ray reflector; and  wherein said x-ray reflector reflects an incident beam in two directions independently.  a Kirkpatrick-Baez side-by-side optic which redirects x-rays, wherein said Kirkpatrick-Baez side-by-side optic has multi-layer Bragg x-ray reflective surfaces, and wherein said Kirkpatrick-Baez side-by-side optic is radiationally coupled to a microfocused x-ray source. 2. The x-ray directing system of claim 1, wherein said multi-layer Bragg x-ray reflective surfaces have graded-d spacing. 3. The x-ray directing system of claim 2 wherein said graded-d spacing is lateral grading. 4. The x-ray directing system of claim 2 wherein said graded-d spacing is depth grading. 5. The x-ray directing system of claim 1, wherein said multi-layer Bragg x-ray reflective surfaces have an elliptical surface. 6. The x-ray directing system of claim 1, wherein said multi-layer Bragg x-ray reflective surfaces have a parabolic surface. 7. The x-ray directing system of claim 1, wherein said multi-layer Bragg x-ray reflective surfaces are a parabolic surface and an elliptical surface. 8. The x-ray directing system of claim 1 further including at least one x-ray aperture assembly, wherein said assembly occludes a portion of said x-rays. 9. An x-ray reflecting system comprising: 10. The x-ray reflecting system of claim 9, wherein said multi-layer Bragg x-ray reflector has graded-d spacing. 11. The x-ray reflecting system of claim 10, wherein said graded-d spacing is lateral graded. 12. The x-ray reflecting system of claim 10, wherein said graded-d spacing is depth graded. 13. The x-ray reflecting system of claim 9, wherein said multi-layer Bragg x-ray reflector has an elliptical surface. 14. The x-ray reflecting system of claim 9, wherein said multi-layer Bragg x-ray reflector has a parabolic surface. 15. The x-ray reflecting system of claim 9, wherein said multi-layer Bragg x-ray reflector has a parabolic surface and an elliptical surface. 16. The x-ray reflecting system of claim 9 further including at least one x-ray aperture assembly, wherein said assembly occludes a portion of said x-rays. 17. An x-ray directing system comprising: 18. The x-ray directing system of claim 17, wherein said multi-layer Bragg x-ray reflective surfaces have graded-d spacing. 19. The x-ray directing system of claim 17, wherein said multi-layer Bragg x-ray reflective surfaces have an elliptical surface. 20. The x-ray directing system of claim 17, wherein said multi-layer Bragg x-ray reflective surfaces have a parabolic surface.
