- 요약Visualizing diverse anatomical and functional traits that span many spatial scales with high spatio-temporal resolution provides insights into the fundamentals of biological systems. Light-field microscopy (LFM) has recently emerged as a scanning-free, scalable method allowing for high-speed, volumetric imaging ranging from single-cell specimens to the mammalian brain. However, the prohibitive reconstruction artifacts and severe computational cost have thus far limited broader applications of LFM. To address the challenge, in this thesis, we report Fourier LFM (FLFM), a system that processes the light-field information through the Fourier domain, substantially overcomes the drawbacks of LFM and realizes fast 3D imaging with enhanced spatial resolution and extended imaging depth.In detail, we first established a complete theoretical and algorithmic framework that describes light propagation, image formation, and system characterization of FLFM, which was fully validated on a prototype system by high-resolution, artifact-free imaging of various caliber and biological samples. Based on the frame, we proposed a generic design principle for FLFM and developed two FLFM systems following this protocol for fast, volumetric, high-resolution live imaging, respectively, on whole cells and entire organoids (CHAPTER 1).Next, in CHAPTER 2, we introduce wFLFM, an approach that enhances the resolution of Fourier light-field microscopy (FLFM) through a hybrid wide-field image. The system exploits the intrinsic compatibility of image formation between the on-axis FLFM elemental and wide-field images, allowing for minimal instrumental and computational complexity. The numerical and experimental results of wFLFM present a two- to three-fold improvement in the lateral resolution without compromising the 3D imaging capability compared to conventional FLFM.In CHAPTER 3, we report FLFM using a hybrid point-spread function (hPSF-FLFM) for fast, volumetric, and high-resolution imaging of entire organoids. hPSF-FLFM transforms conventional 3D microscopy and enables the exploration of less accessible spatiotemporally challenging regimes for organoid research. Via 3D observation of the rapid responses of human induced pluripotent stem cells-derived colon organoids (hCOs) to extracellular cues such as osmotic shock and mechanical stresses, we demonstrate the 3D imaging capacity of hPSF-FLFM to offer cellular (x-y: 2-3 μm and z: 5-6 μm) and millisecond-scale spatiotemporal characterization of whole-organoid dynamics that span large imaging volumes (900 μm x 900 μm x 400 μm in x, y, z, respectively), which enables further biomedical applications with similar spatial-temporal traits, such as calcium imaging of 3D human induced pluripotent stem cells-derived cardiomyocytes (3D hiPSC-CMs) and on monitoring heart beating of tadpole for evaluation on cardiac development.In the end, in CHAPTER 4, we proposed FLFM for instant dual-color light-field imaging. By equipping a filter array behind the MLA and allocating elemental images of imaged samples into different channels, we redistribute fluorescent emission among spatial, angular, and chromatic dimensions and enable simultaneously sensing ultrafast biological signals on two channels, which is enabled for FLFM using switchable illumination scheme. We demonstrated its imaging capacity on diverse biological specimens for high-throughput screening and time-lapsed 3D recording of rapid morphological change and functional traits.In summary, we systemically proposed a Fourier light-field scheme for fast volumetric multicolor imaging, including theoretical and numerical models for system description, general instrument design protocol, and optimized data processing algorithm. Equipped with an axially uniformed sampling and a spatially invariant PSF, FLFM fundamentally improves the imaging quality of LFM by mitigating its artifacts near MLA and reducing the reconstruction speed via parallel imaging processing to roughly two orders of magnitude and its highly scalable design enables diverse systems been readily constructed to meet broader imaging needs across various spatial scales. We anticipate FLFM to be a potent tool for imaging diverse phenotypic and functional information spanning broad molecular, cellular, and tissue systems.
