摘要: A scheme to improve the quality in ghost imaging (GI) by controlling the bandwidth of light source (BCGI) is proposed. The theoretical and numerical results show that the reconstruction result with high quality can be obtained by adjusting the bandwidth range of the light source appropriately, and the selection criterion of the bandwidth is analyzed by the power distribution of the imaging target. A proof-of-principle experiment is implemented to verify the theoretical and numerical results. In addition, the BCGI also presents better anti-noise performance when compared with some popular GI methods.
