The present invention provides a flexible noncontact source of wave energy through the use of time reversal. In the preferred embodiment a differential laser vibrometer is employed to measure the vibration of a sample surface. Thus, the time reversal noncontact source can be configured to provide an out of plane vibration source or an in plane vibration source, or any combination of the two.
