It is important to realize real-time online measurement of temperature field for keeping the equipment in the best running state. Temperature measurement by acoustic is a new kind of temperature visualization measurement technology. The accuracy and speed of the temperature field reconstruction algorithm plays an important role in the application of measuring temperature field. An three-dimensional temperature field reconstruction algorithm based on conjugate gradient is proposed in this paper. Numerical experiments show that the algorithm of image quality is improved obviously compared with those of least squares algorithm.
