【 摘 要 】
A method of temperature measurement based on photoacoustic technique with its noninvasive, real-time, high precision is a new type technology. A cylindrical lens was applied to improve the signal to noise ratio of the detector system in this paper. Then, the relation of photoacoustic signal and temperature were discussed, the corresponding image was obtained. The result indicated that the photoacoustic pressure amplitude presented a good linear relationship at temperature range from 20 °C to 50 °C. The study demonstrated that the photoacoustic temperature measurement approach is feasible.
