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.

FOSREM team is doing a part of the active seismic experiment. All groups installed above 40 sensors and sensors matrix. FOSREM installed four fibre optics sensors – two FOS3 and two FOS5.

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):
With the advance of portable rotation sensor, we expect more rotation observations will be shown in the workshop.
The FOS-5 sensor contains a complete fibre-optic Sagnac interferometer with 250 mm diameter fiber-optics loop, analog to digital conversion circuits, FPGA based digital processing unit for close-loop operation, power conversion and management parts. All of these are placed in a robust case, meeting the IP67 requirements.
This internal digital processing unit provides rotation speed (Omega) value directly in digital form. The FOS-5 has an RS-485 interface for data and USB interface for diagnostic. The connection provides data transmission and power supply from PCU over only one, standard M12 cable within the distance of 500 meters.
