ABSTRACT:
In one embodiment, a system to characterize an anomaly in a laminate structure comprises a plurality of actuators to generate a wave signal into a structure being evaluated, a plurality of sensors to collect scattered wave data caused by energy of the wave signal being at least partially reflected or scattered by an anomaly, and a structural health monitoring unit. In some embodiments the structural health monitoring unit executes a scatter imaging algorithm to generate three dimensional image data for the anomaly from the scattered wave data, extracts a scatter volume from the from the scattered wave data, and generates a damage volume estimate and a damage depth estimate from the scattered wave data. Other embodiments may be described.
