要約(英語): The process tomography (PT) method using ultrasonic waves or electromagnetic waves has been proposed to measure the bubble distribution in a pipe where a liquid containing bubbles flows, but it has a problem of making the equipment larger and more complicated. In this paper, we propose a simpler method for imaging the distribution of air bubbles in a pipe by using an M-sequence coded array probe as the ultrasonic transmitter and receiver. In this paper, the effectiveness of the proposed method was verified by simulation using the finite difference time domain (FDTD) method and actual experiments. As a result, it was found that it was possible to image objects in a circular area in water in both simulation and actual experiments, suggesting that this method can be used to instantly image objects flowing in a pipe.
