Acoustic tomography for 3D temperature and CO{sub 2}-concentration measurements of an environmental field (CT algorithm for axisymmetric field and experimental verification)
- Mie Univ., Tsu (Japan)
Noncontact and nondestructive measurements for determining temperature and CO{sub 2}-concentration distributions in environmental fields are under investigation by acoustic tomography. A new method to reconstruct the three-dimensional temperature and CO{sub 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 numerical reconstruction process is also offered. An experimental system consisting of several pairs of ultrasonic sensors is established to apply the new method to axisymmetric temperature and CO{sub 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.
