Photoacoustic imaging with a synthetic aperture focusing technique (SAFT) is an effective method to improve the lateral resolution for out-of-focus regions in scanning microscopy systems, which commonly require a decent motorized scanning stage for a lateral scan of a transducer to obtain a cross-sectional image. In this study, we propose and test a photoacoustic imaging system with a scanning mirror-based SAFT (SM-SAFT) for simple and fast data acquisition, without the need for a physical scan of the transducer. Photoacoustic images of hair phantoms acquired by SM-SAFT are demonstrated, serving as a proof-of-concept experiment to show the feasibility and potential of the proposed approach.

基于扫描镜的合成孔径聚焦技术的光声显微镜

使用合成孔径聚焦技术（SAFT）的光声成像是一种有效的方法，可以提高扫描显微镜系统中离焦区域的横向分辨率，该系统通常需要像样的电动扫描台才能对换能器进行横向扫描，从而获得换能器。横截面图像。在这项研究中，我们提出并测试了基于扫描镜的SAFT（SM-SAFT）的光声成像系统，以实现简单，快速的数据采集，而无需对换能器进行物理扫描。演示了通过SM-SAFT获得的头发幻影的光声图像，作为概念验证实验，表明了该方法的可行性和潜力。
