ABSTRACT:
A solid state x-ray detector has a set of bilayers formed on its front surface. Each bilayer includes a spacing layer and an absorbing layer which have different indexes of refraction, and the impinging x-rays strike the bilayers at an angle which satisfies the Bragg condition. As a result, x-rays polarized in one direction are substantially reflected while x-rays polarized in an orthogonal direction pass through the bilayers for detection by the solid state x-ray detector.
