Whereas modern digital cameras use a pixelated detector array to capture images, single-pixel imaging reconstructs images by sampling a scene with a series of masks and associating the knowledge of these masks with the corresponding intensity measured with a single-pixel detector. Though not performing as well as digital cameras in conventional visible imaging, single-pixel imaging has been demonstrated to be advantageous in unconventional applications, such as multi-wavelength imaging, terahertz imaging, X-ray imaging, and three-dimensional imaging. The developments and working principles of single-pixel imaging are reviewed, a mathematical interpretation is given, and the key elements are analyzed. The research works of three-dimensional single-pixel imaging and their potential applications are further reviewed and discussed.
虽然现代数码相机使用像素化探测器阵列来捕获图像，但单像素成像通过使用一系列掩模对场景进行采样，并将这些掩模的知识与使用单个像素探测器测量的相应强度相关联来重建图像。虽然在传统的可见成像中表现不如数码相机，但单像素成像已经被证明在非传统应用中具有优势，例如多波长成像、太赫兹成像、X 射线成像和三维成像。本文回顾了单像素成像的发展和工作原理，给出了数学解释，并分析了关键要素。进一步回顾和讨论了三维单像素成像的研究工作及其潜在应用。
