Reflective surface shape controllable mirror device, and method for manufacturing reflective surface shape controllable mirror

摘要

The device is configured from: a reflective surface shape controllable mirror in which a band-shaped X-ray reflective surface 2 is formed on a central portion of a front surface of a substrate 1, reference planes 3 are formed along both sides of the X-ray reflective surface, and a plurality of piezoelectric elements 4 are attached to at least one of front and back surfaces of the substrate so as to be arranged in the longitudinal direction of the X-ray reflective surface on both side portions of the substrate, and a multichannel control system for applying a voltage to each of the piezoelectric elements.

1. A reflective surface shape controllable mirror device for reflecting an x-ray beam in the soft and hard x-ray regions to thereby change a wavefront of the x-ray beam into an ideal wavefront, the reflective surface shape controllable mirror device comprising:
A reflective surface shape controllable mirror; the mirror including A substrate having a front surface and a back surface, A band-shaped x-ray reflective surface formed on a central portion of the front surface of the substrate with desired accurate precision, Reference planes formed along both sides of the x-ray reflective surface with desired accurate precision, Wherein shapes of the x-ray reflective surface and the reference planes are measured, and wherein the shapes and relative shape difference therebetween are calculated to be obtained as initial shape data, A plurality of piezoelectric elements attached to the front surface or the back surface of the substrate in lines along lateral sides of the reference planes so as to be arranged in the longitudinal direction of the x-ray reflective surface on both side portions of the substrate so as to be symmetric with respect to the x-ray reflective surface, and A plurality of-piezoelectric elements attached to an opposite surface of the substrate in such manner that the piezoelectric elements are arranged in lines so as to be symmetric with respect to the x-ray reflective surface, and A multichannel control system for applying a voltage to each of the piezoelectric elements.
