Abstract
A non-contact vibrometer is employed to measure seismic energy imparted to the earth by a land vibrator. The non-contact vibrometer can be a laser vibrometer operable to measure the motion of a baseplate of the land vibrator. A computing device can be used to record both the imparted seismic energy detected by the non-contact vibrometer and reflected seismic energy sensed with geophones.
