An evaluation of single plane ultrasonic tomography sensor to reconstruct three-dimensional profiles in chemical bubble column

In this paper we evaluated a single plane ultrasonic tomography sensor and performed some experimentation to reconstruct three-dimensional profiles in a chemical bubble column. An array of 32 ultrasonic sensors was constructed and clamped on the exterior circumference of the column. The information of the profiles was captured based on time-of-flight and arrival-time analysis. Several phantom profiles were created and sampled using ultrasonic tomography techniques and the results were compared with high-speed camera images. The findings showed promising results where the reconstructed three-dimensional profiles matches with the high-speed camera images.
