Leveraging FSPI for object detection holds promising applications. However, considering the imaging speed of FSPI, it is necessary to obtain the imaging scene information in the under-sampling condition. The quality of FSPI reconstructions with low sampling rate is low and utilizing low quality reconstruction results for object detection will lead to low detection accuracy. To address the challenges, a joint reconstruction-detection framework based on FSPI is proposed. The Spatial-Adaptive Reconstruction Network (SARN) is designed to rapidly reconstruct the low-sampling rate image to improve the image quality. The Mixed Spatial Pyramid Pooling Fast (MSPPF) and Deformable Convolution (DCN) are integrated into the object detection network to improve the detection performance. Through joint training strategy, the synergy between high-level and low-level vision tasks is strengthened, so as to further improve the detection accuracy. Numerical simulations and real-world experiments show that the proposed method not only improves the quality of FSPI reconstruction with low sampling rate, but also significantly improves the performance of object detection tasks.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"16 6","pages":"1-12"},"PeriodicalIF":2.1,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10750336","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrated key distribution is an important means to reduce the deployment cost, as key exchange and public transmission are performed over the same channel. In this paper, we propose a novel method for integrated key distribution by optical steganography based on dither-remodulation in a bias controller of the Mach-Zehnder modulator. No extra wavelength or bandwidth is used for the stealth channel, which is transmitted together within the public channel. The concealing depth of the stealth signal reaches −36.2 dB, and its steganographic effect provides additional security, which further improves the overall security of the optical physical layer. The bidirectional stealth transmission can support light-weight temporary key exchange mechanism, combined with asymmetric encryption algorithm, to achieve high security and forward/backward security of seed keys. We experimentally demonstrate a real-time integrated key distribution via optical steganography in a QNSC system. The experimental results show that a real-time bidirectional stealth link is established at a rate of 1 kbps in a fiber transmission distance of 97 km for a public QNSC transmission at a rate of 32 Gbps, providing a seed key refresh frequency of over 1 Hz.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"16 6","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10750337","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distributed fiber acoustic sensing (DAS) is a novel seismic monitoring system with existing optical communication fiber as sensors and the passive seismic transducers are opt to densely deploy in harsh earthquake prone area, saving valuable time for earthquake to reach sensors. In order to shorten the earthquake identification time and increase the accuracy of earthquake identification at the same time, a fast earthquake identification method is proposed with DAS and DSR-Net (DAS Seismic Recognition Network) deep learning network. The signal time-frequency image samples are constructed to extract signal features, and DSR-Net is used for recognition. The feasibility is verified in natural earthquake monitoring, and the recognition accuracy of the first 5s seismic data is up to 88.29%. As the duration of the earthquake increases, the recognition accuracy reaches more than 93%.

Anti-spoofing research in OCT includes both static and liveness anti-spoofing. Liveness anti-spoofing is commonly detected by additional detection equipment or by extracting the liveness information from the OCT data. However, previous methods suffer from long data acquisition and computation times as well as low recognition accuracy. To address these problems, this paper proposes a fast liveness anti-spoofing method. The method requires no additional detection equipment, is fast in data acquisition and calculation, and has high computational accuracy. This study not only explores the method's effectiveness but also performs parameter analysis and optimization on multiple scales. In addition, this paper presents a comprehensive mathematical model that enables various types of OCT devices to calculate the optimal anti-counterfeiting parameters under different conditions.

The bandgap of VP varies with thickness, ranging from 1.68 to 2.02 eV, with a high responsivity in the visible range. Combining lanthanide-doped upconversion nanoparticles (UCNPs) with VP and taking advantage of the energy transfer between them is a feasible strategy to achieve near-infrared (NIR) photodetection and expand the application scenarios of devices. In this work, we designed a novel strategy for NIR detection by simply combining UCNPs and VP using the spin-coating method. The prepared UCNPs/VP photodetector exhibits an excellent photoresponsivity of 2.8 mA/W and a high specific detectivity of 2.04×10\u0000<sup>9</sup>\u0000 Jones (@ 980 nm, 2.8 mW/cm\u0000<sup>2</sup>\u0000, 10 V). Compared to the weak photoresponse of bare VP, the UCNPs/VP device shows a significant improvement in photoresponse in the near-infrared band. Additionally, we conducted the photoresponse characterization of the UCNPs/VP device at different temperatures, aiming to enhance its performance by adjusting the temperature. In conclusion, we found that the hybrid device performs better in high-temperature environment.
