    • A manufacturing method of a liquid crystal optical device is provided including an alignment film forming step of forming an alignment film containing silicon oxide on a substrate, and a liquid crystal cell forming step of disposing a pair of substrates at least one of which the alignment film has been formed on, opposite to each other interposing a liquid crystal therebetween. In the alignment film forming step, the substrate surface is bombarded with a plasma beam generated by vacuum arc discharge using a cathode containing silicon, where the substrate is disposed on the course of the plasma beam obliquely with an angle. When the plasma beam bombards the substrate surface, plasma ions in the plasma beam have higher kinetic energy or higher flux density than plasma ions in a plasma beam which, if bombarding the substrate obliquely at the angle, form a film having a column structure.
    • 提供了一种液晶光学器件的制造方法,包括:在基板上形成含有氧化硅的取向膜的取向膜形成工序;以及液晶单元形成工序,配置一对基板,至少其中一个取向膜 彼此相对地形成在其间插入液晶。 在取向膜形成步骤中,使用包含硅的阴极通过真空电弧放电产生的等离子体束来轰击衬底表面,其中衬底以等角度倾斜地设置在角度上。 当等离子体束轰击衬底表面时,等离子体束中的等离子体离子具有比等离子体束中的等离子体离子更高的动能或更高的通量密度,如果以倾斜方式以该角度轰击衬底,则其形成具有柱结构的膜。

    • A X-ray waveguide includes a core for guiding X-rays having a wavelength band in which the real part of refractive index of material is smaller than 1 and a cladding for confining the X-rays in the core. The core has a one-dimensional periodic structure in which a plurality of layers respectively formed of inorganic materials having different real parts of refractive index are periodically laminated. The core and the cladding are configured so that a critical angle for total reflection for the X-rays at an interface between the core and the cladding is larger than a Bragg angle due to a periodicity of the one-dimensional periodic structure. A critical angle for total reflection for the X-rays at an interface between layers in the one-dimensional periodic structure is smaller than the Bragg angle due to the periodicity of the one-dimensional periodic structure.

    • An X-ray holography light source element divides an entering X-ray beam to emit two or more mutually coherent X-ray beams. The light source element includes an X-ray waveguide which has a core and a cladding. The core contains a plurality of substances different in a refractive-index real part and is a periodic structure body in which basic structures are periodically disposed; the cladding confines an X-ray to the core to be guided therethrough. The total reflection critical angle of the X-ray on the interface of the core and the cladding is larger than the Bragg angle corresponding to the periodicity of the basic structures of the core. A shield member provided with two or more opening portions for respectively emitting the two or more mutually coherent X-ray beams is disposed at the end portion at an emission side of the X-ray waveguide.
