摘要

Applications of ghost imaging are limited by the requirement on a large number of samplings.Based on the observation that the edge area contains more information thus requiring a larger number of samplings,we propose a feedback ghost im-aging strategy to reduce the number of required samplings.The field of view is gradually concentrated onto the edge area,with the size of illumination speckles getting smaller.Experimentally,images of high quality and resolution are successfully reconstructed with much fewer samplings and linear algorithm.
