Abstract
We present a new method for sensitive ultrasound detection using an open-cavity optoacoustic sensor. Our results have demonstrated significant enhancement of detection sensitivity when the open-cavity sensor is used in media with large isothermal compressibility. A near-linear relationship between detected optoacoustic signal strength and isothermal compressibility has been found.
摘要
我们提出了一种新的利用开放式腔光声传感器进行灵敏超声检测的方法。我们的结果表明，当开放式腔传感器用于具有较大等温压缩性的介质中时，检测灵敏度有显著提高。我们发现检测到的光声信号强度与等温压缩性之间存在近乎线性的关系。
