Abstract
System for optical seismic surveying of an area of interest including at least one seismic source, at least one laser source, at least one optical sensing system and a processor, the processor being coupled with the seismic source, the laser source and the optical sensing system, the seismic source for generating at least one seismic wave in the area of interest, the laser source for generating a matrix of laser spots over the area of interest, the optical sensing system for detecting reflections of the laser spots as a speckle pattern, wherein the seismic source modifies the speckle pattern and wherein the processor determines at least one property of the seismic wave according to the modified speckle pattern thereby generating a seismic map of the area of interest.
