Miniaturization of imaging systems has become an important requirement for studying the brains of freely behaving animals (mice, birds, etc.). The author presents a 1-photon miniscope device with significant mechanical (weight: 1.3g, small size: 10mm $\times17$ mm $\times12$ mm) and optical (lateral resolution: 1 $\mu \text{m}$ , magnification: 12.5, etc.) advantages compared to existing systems. This device can be used to image and study fine brain structures and its design is well-suited for the incorporation of future generations of depth scanning, aberration correction, structured illumination and wireless approaches.

轻量级 1 光子微型显微镜，用于以亚细胞分辨率对自由行为的动物进行成像。

成像系统的小型化已成为研究自由行为动物（小鼠、鸟类等）大脑的重要要求。作者展示了一个具有显着机械性能的单光子微型设备（重量：1.3g，小尺寸：10mm $\times17$ 毫米 $\times12$ mm) 和光学（横向分辨率：1 $\mu \text{m}$ , 放大倍数：12.5 等) 与现有系统相比的优势。该设备可用于对大脑的精细结构进行成像和研究，其设计非常适合结合未来的深度扫描、像差校正、结构化照明和无线方法。
