Improvement by Removing the Conjugate Image for In-line Fresnel Electron Holography

Abstract

In-line Fresnel electron holography has a possibility to be a phase retrieval technique of an isolated object with high precision, though a defocused conjugate image is superposed to a reconstructed image and modulates phase information of the object. In this study, we improved a phase image with the procedure of a sequential inference, by removing the conjugate image.
