Technical details in Fourier single-pixel imaging

Abstract It has been almost 10 years since Fourier single-pixel imaging was proposed in 2015. Fourier single-pixel imaging has been extended to 3-D single-pixel imaging, full-color imaging, multi-modality imaging, microscopy, and light-field imaging. It has also been applied to through-fire imaging, image-free object edge detection, image-free fast-moving object tracking, high-speed rotating object imaging, image-free autofocusing, photovoltaic device functionality imaging, and more. This paper addresses students and researchers in different disciplines who are interested in learning about Fourier single-pixel imaging. We aim to provide the readers with a tutorial that teaches fundamental principles and technical details that help the researchers better understand, analyze, and implement Fourier single-pixel imaging.
