FOSREM system awarded the Silver Medal of the Fair as well as Thailand Award for the Best International Invention & Innovation at 49th International Exhibition of Inventions Geneva!
 
It is with great joy and pride that we want to share the great news. We are extremely honored that Elproma Electronics received prestigious awards and distinctions for the FOSREM device during this year’s #GenevaInventions!
 
Thanks to the use of advanced fiber optic technology, FOSREM provides valuable diagnostic data in real time, enabling quick response to potential threats and minimizing the risk of failure.
 
This award is not only a great honor for us, but also a confirmation of our commitment to continuous innovation and excellence in technology. We would like to thank our extraordinary team led by prof. Leszek Jaroszewicz for their hard work, passion and commitment that enabled us to achieve this great success!
 
We would also like to thank the organizers of International Exhibition of Inventions Geneva for this year’s event, during which we could present our unique solution in more detail. This is a great motivation for us to continue developing and providing the highest quality solutions for our clients.
 
We are excited and optimistic about the future of FOSREM and we are looking forward to the next challenges and opportunities this innovative project brings us.

FOSREM’s FOS6 fiber-optic 6C rotational sensor.

Data recorded by Large Fiber-Optic Seismograph was presented in the 27th International Conference on Optical Fiber Sensors (OFS 2022) in Alexandria, Virginia, USA, 29 August – 2 September 2022.

The International Conference on Optical Fiber Sensors was established in 1983 and it is acknowledged as the world’s leading conference on all topics related to photonic sensing technologies. We presented two papers: “Large Fiber-Optic Seismograph detecting the rotation rate caused by natural factors as well as mining activities” as an oral presentation as well as “Towards uniformity of rotational events recording – common test engaging more than 40 sensors including a wide number of fiber-optic rotational seismometers” as a poster presentation. Presentations underlined the rapid development of rotational seismology. We provide appropriate systems for this field based on the optical fibre Sagnac interferometer. The data recorded by the system FOS5-04 confirms its capability to detect changes in Earth’s rotation rate associated with diurnal polar motion, as well as diurnal and semidiurnal tides.

To further expand the functionalities of the presented large fiber-optic seismograph, we plan to construct the next generation of FOS with three perpendicular axes. The ultimate goal is to achieve full six-degree-of-freedom ground-motion data.

IWGoRS 5th International Working Group on Rotational Seismology Sun Moon Lake, Taiwan 2019/09/22 – 26

The 5th IWGoRS workshop will be held at the Teacher’s Hostel, Sun Moon Lake, Taiwan, from September 22-26, 2019. Institute of Earth Sciences, Academia Sinica (IES) will be the local host. The workshop will cover on all aspects of rotational seismology including (but not limited to):

• instrumentation (portable sensors, ring lasers, tilt correction, etc)
• observation of rotations (application domains, best practices)
• array seismology (gradients, strains, rotations)
• data processing, wavefield interpolation, phase separation
• earthquake physics
• volcano seismology
• ocean-bottom observations
• earthquake engineering
• seismic inverse problems

With the advance of portable rotation sensor, we expect more rotation observations will be shown in the workshop.
