Research Interests

My specialties are ultra-precision machining and X-ray optics.
The machining accuracy in ultra-precision machining is at the atomic level. I am developing manufacturing processes to achieve extreme precision in both shape and surface roughness of arbitrary three-dimensional shapes. I am also developing ultra-precise shape measurement methods and ultra-precise electroforming methods. The applications are mirrors for EUV and X-rays with short wavelengths.

I am also developing an X-ray microscope that can observe cells with a high spatial resolution and an X-ray telescope that can observe the solar corona. I am developing mirrors and X-ray optical systems at SPring-8 and SACLA, which are synchrotoron radiation and an X-ray free electron laser facilities, respectively.

In addition, at the SPring-8, I use high-energy X-rays (100 keV) to observe mechanical machining and electrical discharge machining phenomena to elucidate machining science. I aim to develop new tools in collaboration with researchers and companies specializing in various machining processes.

Recently, I am also interested in the automation of the mirror manufacturing process and the development of environmental machining processes in response to the SDGs. Analysis of processing phenomena using high-energy X-rays is opening up new fields of precision machining.
