Introduction

Akira Yasuhara is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electron microscopy, holding a total of 3 patents. His innovative work has advanced the capabilities of electron beam alignment and elemental mapping in microscopy.

Latest Patents

Yasuhara's latest patents include a beam alignment method and an electron microscope. The beam alignment method provides a technique for easily aligning an electron beam with a coma-free axis in an electron microscope. This method begins by tilting the electron beam in a first direction relative to a reference axis and obtaining a first transmission electron microscope (TEM) image. The beam is then tilted in the opposite direction to obtain a second TEM image. The reference axis is incrementally varied to reduce the brightness of the differential image between the power spectra of the two TEM images. Additionally, his patent on elemental mapping image generation describes an electron microscope that acquires images and spectra at each pixel, allowing for the generation of an elemental mapping image of the specimen.
