We describe recent technological progress in multimodal en face full-field optical coherence tomography that has allowed detection of slow and fast dynamic processes in the eye. We show that by combining static, dynamic and fluorescence contrasts we can achieve label-free high-resolution imaging of the retina and anterior eye with temporal resolution from milliseconds to several hours, allowing us to probe biological activity at subcellular scales inside 3D bulk tissue. Our setups combine high lateral resolution over a large field of view with acquisition at several hundreds of frames per second which make it a promising tool for clinical applications and biomedical studies. Its contactless and non-destructive nature is shown to be effective for both following in vitro sample evolution over long periods of time and for imaging of the human eye in vivo.
我们描述了多模态正面全场光学相干断层扫描技术的最新进展,该技术能够检测眼睛中的慢速和快速动态过程。我们表明,通过结合静态、动态和荧光对比度,我们可以实现视网膜和眼前部的无标记高分辨率成像,时间分辨率从毫秒到数小时不等,这使我们能够在三维大块组织内的亚细胞尺度上探测生物活性。我们的装置将大视野下的高横向分辨率与每秒数百帧的采集速度相结合,使其成为临床应用和生物医学研究的一个有前途的工具。其非接触和非破坏性的特性已被证明对于长时间跟踪体外样品的演变以及对人眼进行体内成像都是有效的。
