Computational imaging allows image formation with single-pixel detectors that have no spatial resolution. It has wide-ranging potential applications in fields ranging from biomedical imaging to remote sensing. However, the practical applications of computational imaging are limited due to the high sampling ratio, weak robustness, and low resolution. In this paper, we propose a robust superresolution computational imaging scheme with diffuser-refined illumination and multibucket detection. To increase the reconstruction efficiency, a dual-stream neural network incorporated with a physical model is developed for this imaging scheme, which can reconstruct a high-resolution image in ultralow-sampling-ratio (1.56%) and ultrahigh-noise (4 dB) environments without any data for pretraining. The experimental results demonstrate that the proposed method can increase the spatial resolution by a factor of 2.59 with respect to the diffraction limit of the original imaging system. We also successfully apply this method to image a real biomedical sample and believe that this study provides a computational-imaging framework for complicated practical applications.

The emerging intelligence technologies represented by deep learning have broadened their applications to various fields. Beyond the conventional electronics-based processing systems, the convergence of photonics and artificial intelligence(AI) technology enhances the performance and learning ability of AI. In this review, we propose the concept of an intelligent photonic system(IPS), illustrating it as a developing architecture with three different versions. For each version of IPS, we review several representative *** we discuss the challenges towards an IPS and provide some prospects for the future development.
