Abstract:
1. A soft-field tomography measurement system comprising: a plurality of transducers configured for positioning proximate a surface of an object, wherein the plurality of transducers correspond to a plurality of channels; an excitation driver coupled to the plurality of channels and configured to generate excitation signals for the plurality of transducers; a single reference excitation source from which excitations are generated; one or more derived excitation sources, wherein one or more of the derived excitation sources derive excitations from the single reference excitation source and the derived excitations are applied to each of the plurality of channels; a response detector configured to measure a response at each of the plurality of transducers; and a reduced bit digitizer in each of the plurality of channels configured to digitize a measured response difference between the measured response at one or more of the transducers and at least one of an excitation of the single reference excitation source or an excitation derived from the single reference excitation source or a separate reference.
