1. A non-contact material characterization system comprising:
an excitation generator, wherein the excitation generator is configured to generate a non-contact displacement force directed to an elastic surface or to a volume of material adjacent to the elastic surface, wherein the non-contact displacement force is directed along a direction to move the elastic surface or the volume in the direction;
an ultrasound transducer, wherein the ultrasound transducer is configured to direct a transmit ultrasound signal to the elastic surface or to the volume, wherein the ultrasound transducer is configured to receive a reflected ultrasound signal from the elastic surface or the volume; and
a processor coupled to the ultrasound transducer, wherein the processor is configured to determine a movement characteristic of the elastic surface or the volume based at least in part on the reflected ultrasound signal, wherein the processor is configured to distinguish movement in the direction from movement opposite the direction.
