%X 光声换能器是近年来迅速发展的一种新型器件，它可以将吸收的光能转换为声能并以超声波的形式发射出去。相比于传统压电型超声换能器，光声换能器具有灵敏度高、带宽大、制作工艺简单等优点，在工业无损检测和医学成像领域具有巨大的应用潜力。本文就近年光声换能器的材料组成、制作方法和应用进展进行了综述。<br />
Photoacoustic transducer is a kind of new device developing rapidly in recent years. It can convert absorbed light energy into sound energy and emit it in the form of ultrasonic wave. Compared with the traditional piezoelectric ultrasonic transducer, the photoacoustic transducer has the advantages of high sensitivity, large bandwidth, simple fabrica-tion process and so on, thus leading to the great application potential in industrial non-destructive testing and medical imaging. In this paper, the material composition, fabrication methods and ap-plication progress of photoacoustic transducers in recent years are reviewed.
