Single-pixel imaging (SPI) has been intensively studied in recent years for its capacity to obtain 2D images using a non-pixelated detector. However, the traditional modulation modality using an iteratively refreshed spatial light modulator has significantly restricted its imaging speed, which is a primary barrier to its widespread application. In this work, we propose and demonstrate a new, to the best of our knowledge, SPI scheme using a spinning mask for modulation. An annular binary mask is designed and spun to perform fast spatial modulation, neglecting the iterative modulation modality that limits SPI speed. A multi-spectral SPI system at 100 frames per second is demonstrated, covering a wide range of spectra, from ultraviolet to short-wave infrared light. We believe that this elegant and low-cost scheme will enable SPI to pave its way for practical application.

基于旋转蒙版的单像素相机

近年来，单像素成像 (SPI) 因其使用非像素化探测器获得 2D 图像的能力而得到深入研究。然而，使用迭代更新的空间光调制器的传统调制方式极大地限制了其成像速度，这是其广泛应用的主要障碍。在这项工作中，我们提出并展示了一种新的，据我们所知，使用自旋掩模进行调制的 SPI 方案。设计并旋转环形二进制掩模以执行快速空间调制，忽略限制 SPI 速度的迭代调制模式。展示了每秒 100 帧的多光谱 SPI 系统，涵盖从紫外线到短波红外光的广泛光谱。
