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, and positioned in at least one winding along an engagement surface of the base plate;
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.
