A prototype of full autonomous fiber-optic rotational seismograph designs for detection of the seismic rotational events. AFORS-1/2 based on depolarized FOG directy detects any rotational events with magnitude in range of 10E-9 rad/s. see –> http://fors.m2s.pl
Main parameters:
- sensor loop – D=0.67m, L=15.0 km (SMF28)
- sensitivity – 1.97 – 2.45E-9 rad/s/Sqtr(Hz),
- bandwith – 1.66 – 212.30 Hz,
- signal processing – Autonomous (Telemeter server)
