Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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 th…
