论文摘要
我们基于MATLAB中的K-Wave模拟工具箱建立了一个用于通风梁光声显微镜的模拟平台。样品位于环境中的z方向中间。通过求解Schrodinger方程，模拟了在样品上辐照的通风梁的传播。并通过通风波袋模拟通风梁的强度。模拟结果表明：在A扫描中，随着时间的流逝，光的强度在49ns处达到峰值；在C扫描中，图像与样品一致。这项研究表明，具有较大景深且没有衍射的通风梁可以实现光声微成像系统的景深大深度。模拟平台的建立对于光声显微镜及其在生物医学中的应用的理论研究具有重要意义。
We build a simulation platform for Airy beam photoacoustic microscopy based on K-Wave simulation toolbox in MATLAB. The sample was located in the middle of z direction in the environment. The propagation of Airy beam irradiated on the sample was simulated by solving the Schrodinger equation. And the intensity of Airy beam was simulated by Airy wave pocket. The simulation result showed that: in A-scan, the intensity of light waved over time, reached peak at 49ns; in C-scan, the image agrees with the sample. This research showed that the Airy beam with large depth of field and no diffraction can realize the large depth of field imaging of the photoacoustic microimaging system. The establishment of the simulation platform has a significance for the theoretical research of photoacoustic microscopy and its application in biomedicine.
