Abstract
A system and method for soft-field tomography data acquisition are provided. One system includes a plurality of transducers that correspond to a plurality of channels, and an excitation driver coupled to generate excitation signals for the plurality of transducers. The system also includes a single reference excitation source from which excitations are generated and one or more derived excitation sources. The one or more derived excitation sources derive excitations from the single reference excitation source that are applied to each of the plurality of channels. The system further includes a response detector 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.
