Abstract:
1. A seismic wave source for generating seismic waves, comprising: a housing split in two halves along a plane including a longitudinal axis of the housing, wherein one of the two halves is separated along the entire longitudinal axis from another one of the two halves by a predetermined distance so that ends of the two halves move one relative to another; plural pillars made of piezoelectric elements and positioned inside the housing to have one end in contact with a semi-cylindrical middle portion of one of the two halves of the housing and another end in contact with a semi-cylindrical middle portion of the other one of the two halves of the housing; and an excitation system connected by wires to the plural pillars and configured to provide electrical signals to the piezoelectric elements, wherein upon receiving the electrical signals from the excitation system, the pillars generate forces on the housing thereby generating the seismic waves.
