Abstract
An apparatus comprising a vibration generation system, a vibration measurement system, and an optical system associated with the vibration measurement system, and a controller. The vibration generation system is configured to generate acoustic energy that causes vibrations to occur in the ground. The vibration measurement system is configured to transmit laser beams to the surface of the ground in which the vibrations occur, receive responses to the laser beams, and generate vibration data from the responses. The optical system is configured to direct the laser beams to the surface of the ground such that the laser beams have a selected spatial arrangement relative to the surface. The controller is configured to determine whether an object is present under the surface of the ground using the vibration data.
