1. A system for identifying defects in a structure comprising:

  • a flexible sheet of material positioned adjacent to the structure;

    a plurality of non-destructive sensors secured to the flexible sheet;

    a mechanism operable to externally apply a plurality of impacts onto the flexible sheet and/or onto the structure proximate to the flexible sheet at a plurality of locations to generate stress waves within and along a surface of the structure, wherein the mechanism is operable to externally apply each impact onto the flexible sheet at a different predetermined location and with a predetermined magnitude; and

    a data acquisition system capable of communicating with the sensors such that the data acquisition system generates feedback indicative of at least a portion of the structure based on accumulated data from the stress waves acquired by the sensors and further based on the predetermined location and the predetermined magnitude at which each of the plurality of impacts is applied.
