FOSREM’s FOS6 fiber-optic 6C rotational sensor.
The 6th IWGoRS Workshop was held at the Institut de Physique du Globe (IPG) in Paris. The workshop re-focused on every aspect of gradient-related ground motion, including rotation and deformation recording, instrumentation, earthquake sources, custom rheology, inverse problems, surveying, seismic engineering, long-term seismology, planetary seismology, derivative rotation and strain, correlation studies noise, ring laser technology, Earth rotation, seismic decoupling, fundamental physics, and more.
Anna Kurzych Ph.D., from FOSREM team showed presentation: “Recording of the rotational events in Poland – Time horizon & Fascinating Future of Fiber-Optic Seismograph”
Members of the 6th IWGoRS Workshop
Anna Kurzych Ph.D. and Jerzy K. Kowalski Ph.D. show the sensor and its applications.
The International Timing and Sync Forum, the world’s largest event on timing and synchronisation, kicked off on Nov 7th in Düsseldorf. For years, industry leaders have been coming together at the conference to showcase their companies’ latest synchronisation solutions.
All visitors are welcome to visit the Elproma Electronics booth, where Tomasz Widomski will answer all questions related to the revolutionary www.fosrem.eu project and modern time servers www.elpromatime.com
FOSREM – the next generation Multipurpose Earth & Space Photonic Sensor with Big Data output for FOG (gyroscopes) and seismograph dedicated for ROTATIONAL SEISMOLOGY
During September 18-22, 2022, Paris, France, will host the world’s most important event in the space sector – the International Astronautical Congress (IAC). On this occasion, the Polish Space Agency (POLSA) will organize an exhibition booth promoting the Polish space sector. The POLSA booth will additionally provide a gathering point for representatives of the Polish space sector at IAC, so that participants may conveniently meet with Polish aerospace companies in one location.
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.
We showed the new FOS6 photonic sensor at the POLSA (Polish Space Agency) stand.
Tomasz Widomski presented our solution at Photonics 4 Defence workshop at MSPO 2022 – PPTF:
Our stand at MSPO:
The pending FOSREM project new technology will be presented and explained in 2022 during 30th International Defence Industry Exhibition MSPO. We show our FOS6 project, especially in future defence applications. You can get information about the project and possible applications at the stand (B-23) of the Polish Space Agency (POLSA).
We will be there! We will show our new FOS6 solutions and the system of ultra-precise synchronisation of seismological measurements.
https://www.gov.pl/web/ncbr-enIn January 2022, we started a new project, FOS6, the 3-dimensional precise FOG-based seismometers. We got €1.5 mln funding from the National Centre for Research and Development. Our team is now part of Elproma Elektronika. We implemented this project together with the Lodz University of Technology.
FOSREM team replaced the previous FOS1 sensor with the new FOS5LL with a 15 km long fiber loop. The old one was working since July 2017 and give us a lot of data. The new FOS5LL (Long Loop) is ten times more accurate, has a long 15000 m fiber optic loop and 1.5 m diameter. It’s working in a closed-loop configuration with 1310nm light.
