Abstract: Methods and systems are provided for inducing seismic vibrations into an elastic medium such as subterranean formations. The methods and systems utilize seismic transducers having a sensor matrix for measurement of baseplate force distributions. Certain embodiments include a sensor matrix that is configured to measure a distribution of discrete force measurements across the surface area of the baseplate. Advantages of including such sensor matrices include a more accurate prediction of seismic transducer energy output. That is, these measurements can be used as feedback to adjust the operation of the seismic transducer. Additionally, these force measurements may be used to provide for a better interpretation of gathered seismic data. These advantages ultimately translate to improved seismic surveys, having higher resolution of the formations surveyed and reaching greater depths.
