Airy-beam large volumetric photoacoustic microscopy

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.
