In this paper, we make full advantage of the information correlation subaperture images and propose a new super-resolution (SR) reconstruction method based on spatiotemporal to achieve SR for light-field images. Meanwhile, offset compensation optical flow spatial transformer network is designed realize accurate between adjacent After that, obtained with high resolution are combined self-designed system phase similarity 3D structured light field. Finally, experimental results demonstrate validity proposed perform from data. Generally, our makes use redundant different images, hides upsampling process in convolution, provides more sufficient information, reduces time-consuming procedures, which efficient

We propose an imaging method based on optical fiber bundle combined with micro-scanning technique for improving image quality without complex reconstruction algorithms. In the proposed method, a piezoelectric-ceramic-chip is used as micro-displacement driver of bundle, which has advantages small volume, fast response speed and high precision. The corresponding displacement can be generated by precise voltage controlling.
