Abstract
Panoramic ghost imaging (PGI) is a novel method for enlarging the field of view (FOV) of ghost imaging (GI), allowing for the practical application of GI. However, the imaging resolution is limited because of the hardware technology. To achieve the coexistence of high resolution and large FOV of GI, the sub-cell pattern shifting method (SCPS) based on the rotation and scaling invariances (RSI) of the log-polar annular pattern structure is proposed to reconstruct higher-resolution PGI from the panoramic ghost images with sub-pixel shifting. Results show that the SPCS can improve the resolution of PGI with the same total number of measurements and reduce the noise to ensure that the PGI with high-quality can be obtained. This method provides a potential way to promote the practical application of GI with high quality and large FOV.
