Abstract
An X-ray imaging system that produces one or more fan-shaped beams is described. The system includes a target for emitting X rays that includes at least one target focal spot, and one or more graded multilayer optic devices in optical communication with the target. The optics transmits at least a portion of the source X rays to produce the one or more fan-shaped beams. The graded multilayer optic devices include at least a first graded multilayer section for redirecting and transmitting X rays through total internal reflection. The graded multilayer section includes a high-index layer of material having a first complex refractive index n, a low-index layer of material having a second complex refractive index n, and a grading zone disposed between the high-index and low-index layers of material. The grading zone includes a grading layer having a third complex refractive index nsuch that Re(n)>Re(n)>Re(n).
