Fluorescence microscopy has become an indispensable tool for visualizing subcellular structures and dynamic biological processes. Light sheet fluorescence microscopy (LSFM), characterized by selective plane illumination and detection, has attracted increasing attention in recent years owing to its low phototoxicity, high spatiotemporal resolution, and large field of view. The emergence of single-objective light sheet systems has further enhanced sample compatibility and system flexibility, opening new avenues for multiscale, long-term, and three-dimensional dynamic imaging. Here, we review the development and diverse configurations of LSFM, with a particular focus on the technical principles, representative applications, and performance advantages of single-objective systems. We also discuss their current bottlenecks in terms of field of view, optical path complexity, and signal transmission efficiency, and explore the potential of zoom-free multiscale single-objective platforms that integrate structural innovations, multimodal imaging, and intelligent control, aiming to provide a reference for the creation of high-performance, bio-friendly, and broadly applicable imaging systems.
