My name is Kazuto Yamauchi and I am a new member at the Photonics Center. “Light” for me is X-rays and, therefore, I would like to describe some of the developments in X-ray optics while telling you a little about myself.

X-rays were discovered in 1895 by Wilhelm Röntgen. In 1912, less than twenty years later, Max von Laue discovered the diffraction of X-rays by zinc sulfide crystals, and the following year William H. and William L. Bragg, father and son, presented Bragg’s law. These brilliant achievements gave us light that enabled humans to see atoms, the greatest beneficiary of which is the field of crystal structure analysis. A hundred years later, the U.N. General Assembly proclaimed 2014 to be the International Year of Crystallography, showing just how much X-rays have contributed to crystallography. In the meantime, optics and crystallography have grown immensely, through mutual stimulation, and have dramatically improved the performance of light sources. Higher throughput has been the greatest need for crystal structure analysis, and particularly for the structural analysis of proteins. X-rays in the form of synchrotron radiation sources have shown rapid advancements in brilliance since around 1990. As a result, X-rays acquired the byproduct spatial coherence, which had not been particularly needed for crystal structure analysis, and a new discipline called coherent X-ray optics was born at synchrotron radiation facilities such as SPring-8. While it is somewhat misleading to say, their function as a tool for viewing matter may have brought X-rays back to the forefront of science.
