Method and apparatus for measuring seismic parameters of a seismic vibrator
First Claim
1. A sensor pad for measuring seismic parameters of a seismic vibrator, the seismic vibrator for generating seismic waves through a geological formation, the seismic vibrator having a base plate positionable adjacent a ground surface of the geological formation, the sensor pad comprising:
- an optical cable positionable between the base plate of the seismic vibrator and the ground surface of the geological formation;
a laser for passing a light through the optical cable; and
a detector for detecting disturbances in the light whereby a ground force of the seismic vibrator may be determined.

Abstract
Apparatus and techniques for measuring seismic parameters, such as ground force, of a seismic vibrator used for generating seismic signals through a geological formation are provided. The seismic vibrator has a base plate positionable adjacent a ground surface of the geological formation. A sensor pad may be provided with an optical cable positionable between the base plate of the seismic vibrator and the ground surface of the geological formation, a laser for passing a light through the optical cable, and a detector for detecting disturbances in the laser light whereby a ground force applied to the ground surface may be determined.
