Noncontact and nondestructive measurements for determining temperature and CO_2-concentration distributions in environmental fields are under investigation by acoustic tomography. A new method to reconstruct the three-dimensional temperature and CO_2-concentration distributions from the projected ultrasonic phase differences is proposed in this paper. A set of programs to evaluate the projected data is made and a numerical reconstruction process is also offered. An experimental system consisting of several pairs of ultrasonic sensors is established to apply our new method to axisymmetric temperature and CO_2-concentration fields. The temperature profiles reconstructed by the present acoustical tomography agree well with the results of the thermocouple measurements. As a result, the procedure proposed in this paper is verified to be reasonable.
