提出了一种用于超声无损评估（NDE）和临床诊断的创新光声源。其工作原理基于激光脉冲热转换成直接蒸发到光纤尖端上的金属薄膜。所提出的换能器的吸引人的优点是高频、大带宽和良好的效率。
An innovative photoacoustic source for ultrasonic non destructive evaluation (NDE) and clinical diagnosis is proposed. The working principle is based on thermal conversion of laser pulses into a metallic film evaporated directly onto the tip of an optical fiber. Attractive advantages of the proposed transducer are high frequency, large bandwidth and good efficiency.
