The use of multi-aperture cameras is one of the modern trends for imaging devices, both consumer-grade and professional. This paper presents the creation of multi-aperture cameras based on long-focus single diffraction lenses. These lenses are several times better than the common lenses in terms of weight and cost, but they are significantly inferior in quality of the resulting image, and therefore they require computational reconstruction stage. We introduce various schemes of multi-aperture diffraction lenses, allowing to increase both the viewing angle and the resolution of the imaging system. We propose a convolutional neural network for image reconstruction in multi-aperture diffraction optical systems.
