title = "A bender element system for measuring shear wave velocities in centrifuge models",
abstract = "A multi-source, multi-receiver bender element system was developed to measure shear wave velocities in centrifuge models. Up to eight source benders can be excited by a high-voltage power supply while up to sixteen receiver bender elements can be used to detect the transmitted signal. Analog band-pass filters are used to remove unwanted signals prior to amplification. Phase distortion caused by the analog filters is corrected by a digital transfer function that reverses the filter effects. Ambient vibrations during spinning of the centrifuge are further reduced by digital filtering and signal stacking. The resulting signals are of high enough quality for accurate determination of travel time. A stacking algorithm to improve the signal to noise ratio is described.",
