The Summer Camp for Scientific Research in Japan, Zhejiang University College of Optical Science and Engineering, ended successfully in 2019.

Jul 31

From July 7, 2019 to July 13, a team of more than 30 students of College of Optical Science and Engineering, led by Professor Lin Yuanfang and Zhang Manhua, went to Japan for a scientific research summer camp.In theseseven days, the team visited the Research Center for Advanced Science and Technology (RCAST) of Tokyo University, the National Observatory of Japan, the University of Electrical Communication (UEC), Hamamatsu Photonics Corporation, Shizuoka University, Hamamatsu Medical University, Hamamatsu Central Research Institute.Andcommunicated severalresearch fields such as photoelectric detection, high power laser, adaptive optics, optical computing, etc.

Research Center for Advanced Science and Technology, Tokyo University (RCAST)

RCAST was established in 1987 and has carried out multifaceted and cross-disciplinary research activities under the four principles of multidisciplinary, mobility, internationalization and openness.RCAST aims to make contributions to the development of science and technology by flexibly responding to the progress of scientific and social changes and developing new fields of advanced science and technology for human and society.

In Tokyo University, Professor Takahashi of the other side took us on a visit. With the comprehensive explanation of Professor Takahashi and his graduate students, we learned about the research progress of RCAST in the fields of super-resolution, three-dimensional imaging, micro-diameter measurement and micro-structure manufacturing, which greatly broadened our vision and broadened our thinking.

In addition to understanding the direction of scientific research, we also experienced the student restaurant of Tokyo University and the student life of Tokyo University under the leadership of the other party.In addition to meals, we also have exchanges with postgraduate students of Tokyo University. From the acquisition of Office of Tokyo University to learning and living, to the local diet culture and living habits, both sides have adopted an inclusive attitude to cross different cultural backgrounds and communicate freely in English.

After experiencing various kinds of delicacies, our trip to Tokyo University ended. While experiencing the life of foreign graduate students, we learned more knowledge and formed friendship with each other.

National Astronomical Observatory of Japan

The National Observatory is the core institution of Japanese astronomy. It has top research institutes and provides large astronomical facilities for researchers all over Japan.

The Observatory is situated in a mountain forest. A set of astronomical equipment on display is full of a sense of age. Students carefully consulted the introduction text and tried to operate some model equipment. They learned some new knowledge about modern astronomical photoelectric detection equipment, traditional astronomical telescopes, equatorial instruments, the origin and structure of the universe.

University of Electrical Communications (UEC)

UEC is the National University of Japan established in 1918. It has a history of more than 100 years and has a strong optical strength.Although it is called "University of Electrical Communications", it is a comprehensive university of science and technology, which combines modern advanced technologies in optics, physics, chemistry and so on.

In UEC, we were warmly welcomed. We visited advanced technology research institutes such as high-power laser research laboratory, laser cooling research laboratory, optical computing research laboratory, comb research laboratory and so on. We were exposed to the progress of many different research fields.After the visit, Mr. Lin Yuanfang and two student representatives were invited to meet with the principal and vice-principal of UEC. Both sides expressed their willingness to cooperate and laid a foundation for future contacts and cooperation.

Hamamatsu Photonics Co., Ltd.

Hamamatsu Photonics was founded in 1953, mainly engaged in research and product production and sales of photomultiplier tubes, imaging equipment, light sources, photoelectric semiconductors, etc. The branch company is located all over the world and has good achievements and influence in related fields.

We mainly visited the Electronic Tube Division and Semiconductor Division of Hamamatsu Photonics.In the electronic tube business department, under the leadership of Mr. Suzuki, we learned about the products of Hamamatsu Photonics in weak light detection, optical fiber bundle glass, ultraviolet static eliminating device and so on, and experienced a lot of product models.

In the Semiconductor Division, due to the limited time, we can only quickly visit the product showroom and learn about the products of Hamamatsu Photonics in photosensitive diodes, optical IC, image sensors, LED, micro-spectrometers and various applications of photoelectric semiconductor materials. It is worth mentioning that the Si strip detector produced by Hamamatsu Photonics has been applied to theLarge Hadron Collider of CERN to detect particle trajectories several microns in length.

Shizuoka University

Shizuoka University is a national comprehensive university. Hamamatsu Campus is mainly the location of its Information Science Department and Engineering Department. The teachers in charge of reception warmly introduced to us the basic situation of Shizuoka University and some surrounding conditions.Then we followed the graduate students of Shizuoka University to visit three laboratories: microscopy, micro-structure manufacturing and microbiology.

A Professor introduced to us the project of using microorganism to purify pollutants and generate electricity. He showed us the results of microbial purification. At the same time, we also know that if microbial power generation technology can be commercialized successfully in the future, it will reduce the energy consumption of sewage treatment (microbial power generation can utilize organic matter in sewage).

Hamamatsu University School of Medicine

Hamamatsu University School of Medicine, founded in 1973, is a medical education and research institution. It aims to train excellent clinicians and aggressive researchers, promote innovative research and development of new medical technologies, and promote human health and welfare.

In Hamamatsu University School of Medicine, Mr. Yang led us to carry out this exchange with Mr. Yamamoto, Vice President. We mainly visited the Biomedical Optics Laboratory, the Nano-coat Institute and the Hardware Stereoscopic Endoscopy Laboratory. We learned about optical technology in medical fields such as optical tomography, in vivo imaging and three-dimensional imaging of biological tissue.

Hamamatsu Central Research Institute

Hamamatsu Central Research Institute is the Research Institute of Hamamatsu Company. Its owner has strong scientific research ability and provides strong technical support for HamamatsuPhotonics.

AtHamamatsu Central Research Institute, their researchers introduced to us the technology of adding reference light to liquid crystal silicon spatial light modulator and feedback optical system to reduce interference fringe disturbance, positron emission computed tomography (PET) technology for cancer detection, phase microscopy technology, photons emitted by algae respiration in water detected by delayed fluorescence excitation device.The technology of algae activity detection, the iPMSEL semiconductor laser, THz laser and organic optoelectronic materials of HamamatsuPhotonics are discussed.

In fact, our institute has a deep relationship with HamamatsuPhotonics. Since 1997, there have been nearly 30 students in Zhejiang University who have developed inHamamatsuPhotonics. One of the company researchers who introduced research projects to us during the visit to the laboratory has a 06-grade graduate. Our Institute has also cooperated with HamamatsuChina.


During this summer camp in Japan, we visited seven research institutes, got in touch with the main research directions and the latest research results of Japanese research institutes, experienced the scientific research atmosphere of Japan in practice, and deeply felt our shortcomings in the comparison.Here, I would like to express my heartfelt thanks to all the units and individuals who have provided support and assistance for this summer camp activity.Special thanks to Mr. Yang of HamamatsuPhotonics for his great help for this event!
