Claim 17:
18. The method of claim 16, further comprising:
generating a first thermoelastic Green's function that provides a magnitude and phase of variation in displacement of the surface of the electronic device over time at a given location at the first frequency as a function of a distribution of heat dissipation within the electronic device in a vicinity of the given location in response to operating the electronic device to dissipate heat in a manner that varies at the first frequency; and
generating a second thermoelastic Green's function that provides a magnitude and phase of variation in displacement of the surface of the electronic device over time at a given location at the second frequency as a function of a distribution of heat dissipation within the electronic device in the vicinity of the given location in response to operating the electronic device to dissipate heat in a manner that varies at the second frequency,
wherein generating the three-dimensional tomographic map of dissipation of heat by the electronic device based on the first plurality of sets of probe measurements comprises solving for a three-dimensional pattern of dissipation of heat within the electronic device using the first thermoelastic Green's function and the second thermoelastic Green's function.
