| Outline of Final Research Achievements |
For super resolution of microscope in soft X-ray region, it was developped that a grazing incidence condeser to illuminate a sample by a structured light and a 5 axes manipulator to obtain phase information of the light passed through a sample. The grazing incidence condenser is developed for strucutred illumination with the use of a point light source. The condenser is composed of toroidal mirrors and the mirror was fabricated and evaluated. A reflection multilayer was deposited on the mirror surface and measured reflectance of the mirror is higher than 0.32 at 4.5 nm wavelength. The 5 axes manipulator was designed and fabricated to obtain phase information of the light, and the average displacement evaluated in x/y/z directions was 25nm/pulse and 2x10^{-6} rad/pulse in θx/θy rotational directions. With the use of these instruments, soft X-ray images of mouse liver-cell stained by Hematoxylin were taken.
