Noncontact and nondestructive visualization of 3D temperature is under investigation by acoustic tomography. A new method to reconstruct the 3D temperature distribution from the projected ultrasonic phase differences is applied to this process in the present paper. With an experimental system consisting of several pairs of ultrasonic sensors, an axisymmetric temperature field is visualized. The whole visualization is realized at three typical cross sections of the temperature field and tries to show the expected 3D images. The temperature profiles reconstructed by this acoustic tomography agree well with the results of the ther-mocouple measurements. As a result, the procedure proposed in this paper is verified to be reasonable.
