Latest Patents

Mori holds a patent for an "Electron microscope and sample observation method using the same." This invention presents an observation apparatus and method that addresses the limitations of the Lorentz method. It allows for the observation of weak scatterers or phase objects with high resolution and no azimuth dependency. The method utilizes a Foucault observation technique with hollow-cone illumination, which orbits and illuminates an incident electron beam at a predetermined inclination angle. The design enables the convergence of an electron wave at a specific position of an aperture plate downstream of a sample. The patent also describes controlling various conditions, such as bright field, dark field, and Schlieren conditions, to achieve optimal spatial resolution by selecting different diameters and shapes of the aperture plate.
