<About the Research>
To make a product, it must be designed, processed, and assembled. In order for a product to perform its designed function, it is important to process and assemble the parts accurately, and also important to evaluate whether the processed parts are manufactured as designed. In particular, it is difficult to find which parts are faulty after the product is assembled, in the cases that the part shape is complex, parts size is small, and the number of parts is large. Based on these backgrounds, in recent years, there has been a need to measure the shape of parts with higher accuracy and speed.

In order to meet such demands, I am conducting research on the dimensional metrology. To assure the accuracy of measurement instruments, a standard, whose dimensions are known accurately, is required. A sphere is one of typical standard shape, therefore, I am developing an ultra-high-precision sphere measurement principle using whispering gallery mode resonance. Besides, in-process measurement is effective for manufacturing products with high accuracy and high yield. In recent project, micro/nano-fibers, which are attracted recently because of uses in medical masks, sensors, materials and so on, is tried to measure. I am proposed the principle of in-process measurement of micro/nanofiber diameters using interferential scattering light.
I also have proposed other novel measurement principles in order to contribute to the development of measurement technology.


<Future aspirations>
Craftsman or Meister have developed manufacturing techniques called craftsmanship through long periods of training by making full use all five senses, including their own eyes, hands, and smells. In the future, unmanned manufacturing will be more developed. I hope to contribute to the future of manufacturing technology by establishing ultra-high-precision measurement technologies that are able to replace the five senses of the craftsman.
