1. A method of detecting explosive devices comprising:

  • exposing an area potentially containing an explosive material in an explosive device to sound waves at a frequency adequate to cause the explosive material to increase in temperature due to a chemical reaction initiated in the explosive material;

    scanning the area to sense an increase in temperature;

    providing a signal indicative of a thermal state of the area after at least a portion of the exposing; and

    determining whether the detected increase in temperature is sufficient to be caused by the chemical reaction in the explosive material.
