A method of Plenoptic imaging with high resolution in turbulent atmosphere

In this paper, we propose and demonstrate an improvement of plenoptic imaging configuration for high resolution imaging with wide field of view in turbulent atmosphere. For the improvement, the plenoptic imaging configuration is equipped with a high resolution conventional imaging system. Plenoptic imaging system is only used for measuring the wavefront distortion of imaging beams. Based on wavefront distortions measured by plenoptic imaging system and blurred images captured by the conventional imaging system, high resolution images can be achieved by the deconvolution of blurred images. Numerical simulations and experimental results show that the improved plenoptic imaging configuration can be used for restoration of near-diffraction-limited images of objects, successfully. Compared with conventional imaging system and plenoptic imaging system, the improved plenoptic imaging configuration combines advantages of wavefront distortion correction, high resolution imaging, wide field of view. The technology proposed in this paper can have wide applications in photo-electric theodolite and large telescopes.
