“…Assume that, the interval distribution of a aperiodic sequence of eight pulses is , it is easy to know that there are at most 4 pulses that can be matched, where the pulses of 3, 5, 7, 11 in i T correspond to that of 1, 5, 3, 20 in j R respectively. Through our scheme, the matching matrix D are shown in Table 1, and its maximum is (6,5) (6,6) 4 DD , same as the analysis above.…”

“…The resolution limit is related to the coherent intensity of the optical field, and the image resolution can exceed the Rayleigh diffraction limit, while the application of compressive perception theory [ 8 ] to GI enables low Nyquist frequency sampling. Numerous advantages of GI make it promising for applications in space remote sensing [ 9 ], optical encryption [ 10 , 11 ], LiDAR [ 12 , 13 , 14 ], medical imaging [ 15 , 16 , 17 ], near-infrared imaging [ 18 ], terahertz imaging [ 19 , 20 ], broadband and hyperspectral imaging [ 21 ], X-ray imaging [ 22 , 23 , 24 ], and imaging of scattering media [ 25 , 26 , 27 ].…”

Ghost imaging is a novel imaging technique that utilizes the intensity correlation property of an optical field to retrieve information of the scene being measured. Due to the advantages of simple structure, high detection efficiency, etc., ghost imaging exhibits broad application prospects in the fields of space remote sensing, optical encryption transmission, medical imaging, and so on. At present, ghost imaging is gradually developing toward practicality, in which ghost imaging of moving targets is becoming a much-needed breakthrough link. At this stage, we can improve the imaging speed and improve the imaging quality to seek a more optimized ghost imaging scheme for moving targets. Based on the principle of moving target ghost imaging, this review summarizes and compares the existing methods for ghost imaging of moving targets. It also discusses the research direction and the technical challenges at the current stage to provide references for further promotion of the instantiation of ghost imaging applications.

In this paper, we introduce a quantum-secured single-pixel imaging technique designed to withstand spoofing attacks, wherein adversaries attempt to deceive imaging systems with fake signals. Unlike previous quantum-secured protocols that impose a threshold error rate limiting their operation, even with the existence of true signals, our approach not only identifies spoofing attacks but also facilitates the reconstruction of a true image. Our method involves the analysis of a specific mode correlation of a photon-pair, which is independent of the mode used for image construction, to check security. Through this analysis, we can identify both the targeted image region of the attack and the type of spoofing attack, enabling reconstruction of the true image. A proof-of-principle demonstration employing the polarization-correlation of a photon-pair is provided, showcasing successful image reconstruction even under the condition of spoofing signals that are 2000 times stronger than true signals. We expect our approach to be applied to quantum-secured signal processing, such as quantum target detection or ranging.
