A close-proximity thermoacoustic sensor that can determine radiated ultrasound intensities by directly coupling a transducer via a coupling medium. The sensor captures the beam, converts the ultrasound power into heat, and indirectly measures the spatial average time average ultrasound intensity (Isata) by dividing the calculated power by the beam-cross-section (or the nominal area of the transducers).
