Leszek R. Jaroszewicz | AFORS – Autonomous Fiber-Optic Rotational Seismograph

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)
