1. Introduction

X-ray Phase Imaging is a new measurement method using synchrotron radiation X-rays, which are known for its useful features; brightness and high directionality. We use two gratings and a sensor to detect the phase of the defraction from the object. Like computed tomography, by illumination every direction of the object, we can got the 3-dimentional structure of this object with its internal information(See Fig.1).

2. Reconstruction

For most of the time in Momose lab my work is study, several research works I had done are not very in-depth. I joined the the experiments in the world's largest third-generation synchrotron radiation facility(Spring-8) and after that did some reconstruction work of the data we got during this experiment(see Fig.2).
