摘要：
A temperature field measurement system based on acoustic sensors is introduced in detail, including a pseudorandom serial sound generator, hardware and software design of the system and the principle of measuring time-of-flight of sound wave using cross-correlation analysis. Using this system and combining with temperature field image reconstruction algorithm based on Gaussian function and regularization method, different flame temperature field image reconstructions are realized. The results of experiments indicate that this system can realize flame temperature field image reconstruction well and the speed of temperature field reconstructing is higher. It will probably be developed an available measurement device of temperature field.
