Abstract
Recently, near-field imaging has been studied in microwaves, optics, and acoustics. In this paper, we study the near-field imaging of wave sources and thus the structure of transducers in high resolution. In addition, we report the near-field imaging of array transducers that were driven with alternating phases on adjacent elements. This produces high contrast images of the array structures. Results suggest that these methods may be useful for transducer manufacturers, designers, and researchers.
