The invention discloses a
system and a method for measuring temperature in real
time based on thermoacoustic effect. A thermoacoustic
signal of a detected material is detected by using
thermoacoustic imaging equipment; a relation parameter of the temperature of the detected material and the thermoacoustic
signal amplitude value is obtained by data fitting; during actual
temperature measurement, by using the known fitting parameters and through the relation of the temperature of the detected material and the thermoacoustic
signal, the temperature of the detected material is obtained by reversely deducing and analyzing by using a one-dimensional thermoacoustic signal; and finally a temperature distribution figure is displayed on a computer in real time. Combined with the advantages of thermoacoustic technology, the
system and the method for measuring the temperature in real
time based on the thermoacoustic effect have high accuracy and
high spatial resolution, and can quickly obtain temperature change parameters and the temperature distribution figure in real time under the condition of no damage, wherein the
temperature measurement accuracy can reach 0.2 DEG C, so a reliable monitoring method and a
system device are provided for real-time and
nondestructive measurement of material temperature.
