Claim Text:
1. An apparatus comprising: an acoustic wave generator configured to simultaneously generate a plurality of acoustic waves that propagate through a laminate along a plurality of in-plane directions; a plurality of acoustic transducers spaced apart from one another and positionable at one or more known distances from the acoustic wave generator along respective in-plane directions, the acoustic transducers being configured to detect acoustic waves propagating through the laminate along the respective in-plane directions; and a processing device coupled to the acoustic transducers and configured to simultaneously calculate a plurality of elastic constants of the laminate as a function of velocities of the acoustic waves detected by the acoustic transducers, the processing device being configured to calculate the velocities as a function of the one or more known distances and arrival times of the acoustic waves at the acoustic transducers.
