本文报道了一种由两根光纤组成的新型光声传感探头的设计。一根光纤用于传递激发光脉冲。另一个作为声学延迟线,将产生的PA信号从目标中继到外部超声换能器。通过适当的延时,可以很容易地将原始扩音信号与干扰信号分离开来。为了证明这种新设计,设计、制造和测试了一个原型探头。研究了不同浓度的黑色和红色染料溶液对PA传感性能的影响。测试结果表明,PA感测探头可以提供良好的灵敏度,并在很宽的浓度范围内保持高线性。检测牛血液嵌入鸡胸组织也进行了证明其潜在的有用性体内应用。
In this paper, we report a new photoacoustic sensing probe design consisting of two optical fibers. One optical fiber is used for delivering the excitation light pulses. The other one serves as an acoustic delay line to relay the generated PA signal from the target to an outside ultrasound transducer. With the addition of suitable time delay, the original PA signal can be easily separated from the interference signals. To demonstrate this new design, a prototype probe was designed, fabricated and tested. The PA sensing performance was characterized with different concentration of black and red dye solutions. The testing results show that the PA sensing probe can provide good sensitivity and maintain high linearity over a wide range of concentrations. The detection of bovine blood embedded into chicken breast tissue was also conducted to demonstrate its potential usefulness forin-vivoapplications.
