大规模快速体积成像一直是生物显微镜的长期挑战。为了解决这一挑战,我们报告了一种增强的共聚焦显微镜的变体,它使用一系列轴向分布在检测空间中的反射针孔,使得每个针孔探测样品内的不同深度。因此,我们获得同时多平面成像,而不需要轴向扫描。我们的显微镜技术是多功能的,并在这里配置为提供双色荧光成像,视场大于一毫米的视频速率。它的普遍适用性证明与线虫和小鼠大脑在体内的神经元成像。
Fast, volumetric imaging over large scales has been a long-standing challenge in biological microscopy. To address this challenge, we report an augmented variant of confocal microscopy that uses a series of reflecting pinholes axially distributed in the detection space, such that each pinhole probes a different depth within the sample. We thus obtain simultaneous multiplane imaging without the need for axial scanning. Our microscope technique is versatile and configured here to provide two-color fluorescence imaging with a field of view larger than a millimeter at video rate. Its general applicability is demonstrated with neuronal imaging of both Caenorhabditis elegans and mouse brains in vivo.
