IEM Seminar Series: What you see beyond Light-in-Flight imaging: History and Future of ultrafast video cameras
Abstract
Almost every day, people enjoy slow-motion video images on TV, such as curving balls in ball games, catching preys of wild big cats and beating wings of honey birds. Prof. Etoh is a pioneer of the high-speed image-sensor technology, and still a leader of the field toward the ultimate high-speed. His lecture covers history, technologies, and what will come in the next ten years, far beyond current technologies. For example, in 2018, his team successfully captured flying light in motion by one shot with their camera. Their target is a 10-ps temporal resolution in which light flies only 3 mm in vacuum and 2 mm in human bodies. Imagine how and to what you could apply this futuristic technology! Many interesting and fantastic ultra-highspeed motion pictures will be shown in the lecture, including a cute lizard running over water, an experimental thunderbolt, flying light, etc.
Bio
Prof. T. Goji Etoh received his Ph.D. from Osaka University in 1973 for his work on floods and water resources controls in the field of civil engineering. Currently, he is a guest professor at Osaka University and an invited professor of EPFL. To visualize and analyze high-speed motions of water, he developed a high-speed video camera of 4,500 frames per second (fps) in 1991, which was fastest in the world and marketed as KODAK EKTAPRO HS4540. The camera was widely applied to visualization of high-speed phenomena in various fields of science and engineering. Since then, he has been renewing the world highest frame rates of high-speed video cameras: 1,000,000 fps (Mfps) in 2002, and 100 Mfps in 2018. He is now targeting a frame rate beyond 100 Gfps (Dt =10 ps), which is the theoretical temporal resolution limit of silicon image sensors. He is recipients of many scientific awards, such as Harold Edgerton Award of SPIE.
