Abstract
A system for detecting source acoustic energy in seismic operations. The system is operable on land and in marine applications. On land, a piezoelectric film is positioned between a vibrator or other source baseplate and the soil. Compression of the piezoelectric film generates an electrical signal proportional to the total ground force, including force due to flexural or resonance of source components, exerted by the seismic source. In marine applications, a source displaces water to produce a pressure pulse in the water, and a piezoelectric film detects the resulting pressure pulse and the flexural movement of the source to produce an electrical signal proportional to the movement of the active component.
