In IR spectroscopy they induce a vibrational response in a material to understand its composition. If we set a series of induced pulsed vibrations in a material would they create a resonance that would transfer through multiple objects or materials in a coherent beam? Could we read the vibrational response in reverse through the beam in the rest phase between pulses? Using time of signal return the variations of vibrational response would be like a core sample through any combinations of material and/or voids.
