The core has a periodic structure made of different substances periodically arrayed perpendicular to a guiding direction. A critical angle for total reflection of an X-ray at a core-cladding interface is larger than a Bragg angle of the periodic structure. A critical angle for the total reflection of the X-ray at a substance interface in the periodic structure is smaller than the Bragg angle. When s is a core width in a direction perpendicular to the guiding direction and parallel to a curvature radius of the curved portion, nlow is a refractive-index real part of the substance having a minimum real part of refractive index, nhigh is a refractive-index real part of the substance having a maximum real part of refractive index, and R is the curvature radius, [s/ln(nhigh/nlow)]

摘要： An X-ray waveguide includes a core having a periodic structure in which basic structures made of a plurality of materials having different real parts of refractive indexes are periodically disposed, a cladding formed on an outer side of the core to confine X-rays in the core through total reflection and including at least a portion with a gap between the cladding and the core, and a driving unit which drives at least a portion of the cladding or the core to change a distance of the gap. A critical angle for total reflection of the X-rays in the interface between the cladding and the gap is larger than a Bragg angle corresponding to the periodic structure of the core, and a critical angle for total reflection in an interface between a plurality of ingredients which form the periodic structure of the core is smaller than the Bragg angle.

摘要： An apparatus includes pixels on a substrate. Each pixel includes a first portion, a second, and a microlens. The substrate has a first surface on an incidence side and a second surface opposite to the first surface, and includes an inter-pixel portion isolating adjacent pixels from each other, and an intra-pixel portion isolating the first and second portions from each other. The inter-pixel portion includes a first region located adjacently to the first surface, and a second region located adjacently to the second surface. The intra-pixel portion includes a third region located adjacently to the first surface, and a fourth region located adjacently to the second surface. The first and third regions are shifted with respect to the second and fourth regions, respectively, in an identical direction that is a direction orthogonal to a longitudinal direction of the intra-pixel portion in plan view from the first surface.
