  • Can not make things that can not be measured.
  • We are conducting ultra precision measurement using light (laser).
  • A laboratory that respects the autonomy of students, it is a very free laboratory.

Supervisor

Professor / Masato AKETAGAWA, Assistant Professor / Wei DONG
Professor Aketagawa has the experience of being a researcher at a company. Therefore, he has wide and deep knowledge about optical measurement technology. We encourage students to study in abroad, respecting our independence, and leading research with precise advice. Assistant Professor Wei always provide us various topics not only also a campus life.

Research Content

In our laboratory we are researching ultra precision measurement system using leaser. We aim to contribute to the development of nanotechnology by considering a method of precision measurement, precision control and precision processing in nano (1 / billionth ) pico (1 / trillion) meter order.
[1]Frequency stabilization and displacement measurement of 780nm DBR laser diode.
[2]Ultra precision measurement of refractive index of air.
[3]Measurement of motion error of bearing: Precise measurement of all 5 degrees of freedom bearing error by all simultaneously.
[4]Length measurement with optical comb.

A Day in the Lab

In our laboratory, no core time, and students has a great responsbility for a management of there resaech. Some people come early in the morning and are studying, others are still late at night. The seminars that are held twice a week are seminars progress seminar and paper seminar. At the progress seminar, we will briefly explain the progress of the research in shearing the lab menbers. In the magazine seminar, We read English articles related to research and deepen their understanding.
The student room is large and has a comvinient facilities such as air conditioning, cooking utensils, coffee makers, etc. For lunch and dinner, we will go to the 1st dining hall and occasionally a cafe "popai".
Throughout the year, there are various events such as a welcome party for newcomers, fireworks festival, year-end party, etc. we would like to have more events in this fiscal year‼
