Rotaphone, a mechanical seismic sensor system for field rotation rate measurements and its in situ calibration
Original language description
A newly developed mechanical sensor system, called a Rotaphone, for recording rotation rate components is described. The sensor system is based on measurements of the differential motions between paired low-frequency geophones attached to a rigid skeleton. The same differential velocity (and, consequently, the same rotation rate component) is obtained from more than one geophone pair, which allows for in situ calibration and matching of the individual sensors. The calibration method, which is a key point of our methodology, is explained in detail and demonstrated on synthetic examples. The instrument and the calibration technique were also subjected to laboratory testing utilizing a rotational shaking table. Some results of these tests are presented incomparison to the data from a reference sensor (fiber optic gyroscope). The new rotational seismic sensor system is characterized by a flat frequency response over a wide range from 2 to 200 Hz and sensitivity limit of the order of 10 (-
