Dimensional fluid mapping systems with multi-frequency excitation

A dimensional fluid mapping system comprising:

• an internal fluid device having one or more internal cavities configured to contain a fluid, the one or more internal cavities having one or more internal features, the internal fluid device having a first side and a second side opposing the first side, and the internal fluid device having first and second depths between the first and second sides;
• a heating device configured to apply heat to the first side of the internal fluid device when driven with a multifrequency excitation signal;
• a thermal measuring device configured to record thermal signals emitted from the second side of the internal fluid device in response to the multifrequency excitation signal;
• and
• a controller configured to receive the thermal signals from the thermal measuring device and to detect an abnormality of the fluid contained in the one or more internal cavities at the first and second depths of the internal fluid device in response to the thermal signals.

• and
• a controller configured to receive the thermal signals from the thermal measuring device, to deconvolute the thermal signals to obtain a multifrequency phase shift thermal map, and to detect an abnormality of the fluid contained in the one or more internal cavities in response to the multifrequency phase shift thermal map.
