基于正交相位检测的迈克耳孙干涉仪光声层析成像
Photoacoustic Tomography using a Michelson Interferometer with Quadrature Phase Detection
摘要：
提出了一种基于迈克耳孙干涉仪的光声层析压力传感器。采用正交相位检测，允许在镜表面上的任何点处进行测量，而不必重新调谐干涉仪，这通常是法布里-珀罗型检测器所要求的。这为临床应用所必需的快速全表面检测打开了大门。利用声压与被测声粒子位移之间的关系理论计算了探测器的灵敏度，并进行了实验验证。血管体模的概念验证断层图像已经在几毫米的深度以亚毫米分辨率拍摄。
英文摘要：
We present a pressure sensor based on a Michelson interferometer, for use in photoacoustic tomography. Quadrature phase detection is employed allowing measurement at any point on the mirror surface without having to retune the interferometer, as is typically required by Fabry-Perot type detectors. This opens the door to rapid full surface detection, which is necessary for clinical applications. Theory relating acoustic pressure to detected acoustic particle displacements is used to calculate the detector sensitivity, which is validated with measurement. Proof-of-concept tomographic images of blood vessel phantoms have been taken with sub-millimeter resolution at depths of several millimeters.
