We introduce Airy-beam tomographic microscopy (ATM) for high-resolution, volumetric, inertia-free imaging of biological specimens. The work exploits the highly adjustable Airy trajectories in the three-dimensional (3D) space, transforming the conventional telecentric wide-field imaging scheme that requires sample or focal-plane scanning to acquire 3D information. The results present a consistent near-diffraction-limited 3D resolution across a tenfold extended imaging depth compared to wide-field microscopy. We anticipate the strategy to not only offer a promising paradigm for 3D optical microscopy, but also be translated to other non-optical waveforms.
我们介绍了用于生物样本高分辨率、体积成像且无惯性的艾里光束断层扫描显微镜（ATM）。这项工作利用了三维（3D）空间中高度可调节的艾里轨迹，改变了传统的远心宽场成像方案，该方案需要样本或焦平面扫描来获取3D信息。与宽场显微镜相比，结果显示在十倍扩展的成像深度上具有一致的近衍射极限3D分辨率。我们预计该策略不仅为3D光学显微镜提供了一个有前景的范例，还能转化到其他非光学波形上。
