Single-shot coded-aperture optical imaging physically captures a code-aperture-modulated optical signal in one exposure and then recovers the scene via computational image reconstruction. Recent years have witnessed dazzling advances in various modalities in this hybrid imaging scheme in concomitant technical improvement and widespread applications in physical, chemical and biological sciences. This review comprehensively surveys state-of-the-art single-shot coded-aperture optical imaging. Based on the detected photon tags, this field is divided into six categories: planar imaging, depth imaging, light-field imaging, temporal imaging, spectral imaging, and polarization imaging. In each category, we start with a general description of the available techniques and design principles, then provide two representative examples of active-encoding and passive-encoding approaches, with a particular emphasis on their methodology and applications as well as their advantages and challenges. Finally, we envision prospects for further technical advancement in this field.

在光中打孔：单次编码孔径光学成像的最新进展

单次编码孔径光学成像在一次曝光中物理捕获编码孔径调制的光信号，然后通过计算图像重建恢复场景。近年来，这种混合成像方案的各种模式取得了令人眼花缭乱的进步，伴随着技术改进和在物理、化学和生物科学中的广泛应用。这篇综述全面调查了最先进的单次编码孔径光学成像。根据检测到的光子标签，该领域分为六类：平面成像、深度成像、光场成像、时间成像、光谱成像和偏振成像。在每个类别中，我们从可用技术和设计原则的一般描述开始，然后提供主动编码和被动编码方法的两个代表性示例，特别强调它们的方法和应用以及它们的优势和挑战。最后，我们展望了该领域进一步技术进步的前景。
