X-ray adaptive zoom condenser utilizing an intermediate virtual focus

Abstract: We propose an extended X-ray adaptive zoom condenser that can form an intermediate virtual focus. The system comprises two deformable mirrors for focusing within a single dimension and can vary its numerical aperture (NA) without changing the positions of the light source, mirrors, or final focus. The desired system NA is achieved simply by controlling the mirror surfaces, which enables conversion between convex and concave forms, by varying the position of the intermediate virtual focus. A feasibility test at… Show more

“…[17][18][19][20][21] Moreover, a hybrid deformable mirror comprising a precision mechanical bender and a bimorph deformable mirror was recently proposed, in which the demerits of the bimorph mirror, such as drifts over time and junction effects, 18 are effectively compensated by the mechanical bender, thereby enabling stable operation. [22][23][24] In the hybrid deformable mirror, the target shape can be generated comprehensively by mechanically applying moments at both ends and distributing the moments induced by piezoelectric actuators on the bimorph mirror. Practically, each of the two bending mechanisms can generate deformation profiles up to third-order polynomials, leading to various combinations of the mechanical bender and bimorph mirror contributions.…”

“…Деформируемые зеркала, использованные в работах [75,76], представляют собой гибридные системы, состоящие из пьезоэлектрического биморфного зеркала и механического изгибного устройства. В этой конфигурации пьезоэлектрические актюаторы на ДЗ вносят очень небольшую коррекцию в погрешность формы после механического изгиба.…”

“…Напротив, в гибридной системе этот эффект значительно снижен, поскольку изгибающий момент обеспечивается механическим изгибным устройством. Поскольку ограничения на изготовление пьезоэлектрических пластин Авторы работ [75,76,79] построили двухступенчатую адаптивную зеркальную систему KБ с использованием четырех пьезоэлектрически деформируемых ДЗ. Использование четырех ДЗ позволило добиться формирования коллимированных рентгеновских пучков с переменным сечением пучка с параллельностью ∼ 1 µrad или фокусировки РЛ с изменяемым размером фокуса без необходимости изменения положения зеркала или образца путем простой деформации четырех зеркал.…”
