An optical-resolution photoacoustic microscope (OR-PAM) with capability of fast axial-scanning was developed by using a tunable acoustic gradient (TAG) lens. The TAG lens was designed to continuously changing the focal plane of OR-PAM by modulating its refractive power with fast-changing ultrasonic standing wave. The performance was shown by imaging a carbon fiber. We achieved a DoF of about 750 μm. The head of a zebrafish was also imaged to further demonstrate the feasibility of our method.
通过使用可调谐声学梯度（TAG）透镜，开发了一种具有快速轴向扫描能力的光学分辨率光声显微镜（OR-PAM）。TAG透镜旨在通过用快速变化的超声驻波调制其屈光力来连续改变OR-PAM的焦平面。通过对碳纤维成像展示了其性能。我们实现了约750μm的景深。还对斑马鱼的头部进行了成像，以进一步证明我们方法的可行性。
