Abstract of Workshop Speech

As a result of the development of new distributed optical fiber strain sensor technology based on Rayleigh scattering, significant improvement in performance has been recently achieved. In this presentation, it is reported that major changes have occurred in sensing for civil engineering structures, focusing on cases in construction management. Structural monitoring by optical fiber sensor based on both Rayleigh and Brillouin scattering can contribute to safe and high-quality construction management for tunnels, bridges and so on. Furthermore, the sensor can be later used for long-term monitoring, during maintenance periods through the structure lifetime. What is seen here is not the continuous performance improvement such as higher spatial resolution and accuracy, but the discontinuous change given to construction management. Visualizing structural behavior by optical fiber sensor, paradigm shift is coming in sensing for civil engineering field

A crucial piece in renewable-energy power-management puzzle lies in the development of renewable energy storage devices such as lithium-ion batteries—poorly-understood degradation mechanisms that occur upon repeated cycling, and that increase the risk of catastrophic battery failure. To develop the next-generation of safe, high-capacity renewable-energy storage, it is therefore crucial to develop methods that monitor the battery’s physical and chemical state-of-health and operation in real-time. Right now, battery assessing methods are typically offline and simulation based. This talk will review the recent developments of in situ fibre-optic analytical technique that will enable us to monitor the state of health of batteries continuously during operation and to minimize their degradation. This method fills a very important gap in current battery monitoring methods, will guide the design of new materials, and will optimize existing and new electro-chemistries.

X-ray imaging is currently considered a ‘gold standard’ in minimally-invasive interventions. It enables physicians to see and guide their medical devices while navigating inside the patient’s anatomy. With recent advances in the field of image-guided therapy, increasingly complex procedures are carried out under X-ray guidance, replacing traditional open surgery. These complex procedures are associated with increased X-ray dose and more contrast agent usage, as well as with longer procedure times. This can pose increased health risks to patients, physicians and staff. At Philips Image Guided Therapy we have already developed solutions for improved visualization and radiation reduction while using X-ray guidance. We are now shaping the future of Philips Image Guided Therapy by developing minimally-invasive devices with integrated Fiber Optic RealShape (FORS) technology. This breakthrough technology enables real-time 3D visualization of the full shape of devices inside the patient’s anatomy, without the need for continuous fluoroscopy. This is realized by sending and receiving light into hair-thin optical fibers integrated into these devices. This presentation will review the basics behind FORS technology and its use in Philips’ medical devices. Results from technical and pre-clinical studies will be summarized and insights from clinical studies will be discussed.

In this presentation, I will introduce Hamamatsu Photonics’ R&D. Hamamatsu is in the center of Tokyo and Osaka and has long been known as a “manufacturing town” represented by the “Yaramaika Spirit (Let’s Do It!)”. Many companies such as Yamaha and Kawai for musical instruments, Honda and Suzuki for motorcycles, and many others were founded here in Hamamatsu. The origin of Hamamatsu Photonics can be traced back to the vacuum tube technology of Prof. Kenjiro Takayanagi, who invented “the world’s first electronic television” at Hamamatsu Technical College (currently Faculty of Engineering, Shizuoka University) in 1926. Hamamatsu Photonics was established in Hamamatsu City in 1953 as an “optical device manufacturer” by Heihachiro Horiuchi (1st president) who had graduated from the Takayanagi Laboratory, and Teruo Hiruma (2nd president). Here, we will introduce the history of Hamamatsu Photonics’ contributions to advanced scientific research, including the development of 20-inch photomultiplier tubes for neutrino detection and Si detectors for Higgs boson detection. We also introduce spatial light modulator technology, which is being put to practical use in super-resolution microscopy and laser processing. We are confident that our mission is to benefit society through the development of technologies that capture, measure, and generate various types of light.

Abstract of Workshop Speech

Fiber optic sensors are widely adopted worldwide, currently. From an industrial point of view, fiber optic sensors may not be a standalone industry, but they are expanding their role in various industries. Especially, due to the increasing need for various sensors in the global trends of unmanned and artificial intelligence, fiber optic sensors are receiving attention as an important enabling technology for satisfying these trends. Among the fiber optic sensor market, there are two major markets: the inertial senor market and the distributed sensor market. FIBERPRO is involved in both of these markets. Currently, the inertial sensor market is much larger in terms of supply, but the distributed sensor market is also gradually growing as the market expands into renewable energy and security monitoring applications. The inertial sensor segment is a market where major companies are major players, like Honeywell, Safran, and etc., each keeping their own domestic markets. The distributed sensor market has a wide variety of applications, and various players with diverse solutions are active in this market. In this presentation, we will focus on the actual commercial products being sold in Korea in the inertial sensor and distributed sensor markets and examine their applications and case examples.
