Abstract
In the paper the concept of optical sensor FORS-II (Fiber-Optic Rotational Seismometer) application for detection of rotation effects occur during seismic events is presented. The main advantage of the FORS-II is its very high sensitivity in the range of about 2.10-8 rad/s. Result of the system research and experimental data comparison with data obtain by two antiparallel pendulum seismometers are also presented. Finally, theoretical concept of observed rotation effects during seismic events is also presented.
