As many sports grounds have a center circle and halfway line, we propose an algorithm that first obtains constraints on the image of the circle center by using homography based on the geometric properties of the circle perimeter and corresponding circumferential angle. Then, the vanishing line is obtained from the image of the circle center and the complete circle image based on the pole-polar relation with respect to the camera internal parameters. By decomposing the circle image, the camera external parameters are obtained to determine the homography matrix from a spatial point to an image point. The camera at the edge of the moving field is calibrated according to the duality of the conic and homography matrices. Using the homography matrix between a point on the moving ground plane and the corresponding image point, the coordinates of the measured point can be recovered to estimate the pose (i.e., position and orientation) of a moving target.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"128 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143582639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By normal ordering the noise operators, we simplified the calculations and derived the evolution equations for the atomic operators using the master equation. From the steady-state solutions, we determined the average of the photon number, the quadrature variance of radiation, entanglement, the normalized second-order correlation of the cavity radiation, the linear correlation coefficient between the two modes, and fluctuations in intensity difference. Our findings indicate that higher spontaneous emission rates significantly decrease the average photon number, while the amplitude of the pumping mode interacting with the parametric amplifier ((varepsilon)) increases it. Enhanced squeezing is observed with increasing ((varepsilon)), reaching a peak at (varepsilon = 0.03) ((72.6%)). Moreover, spontaneous emission enhances squeezing. A direct correlation between squeezing and entanglement is found, with greater squeezing associated with increased entanglement. These insights have significant implications for advancing quantum technologies, such as quantum communication, where controlled squeezing and entanglement improve secure communication channels and signal-to-noise ratios, quantum computing, where they enhance error correction protocols and gate operation efficiencies, and quantum sensing, where they increase sensitivity for more precise measurements of physical quantities.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"16 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143570378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with the CuI/MgZnO self-powered PD, the optimised heterojunction PD (CuI/Cu2O/MgZnO) exhibits significantly improved self-powered properties. Under 325 nm UV light at an intensity of 450 µW/cm2, the CuI/Cu2O/MgZnO heterojunction PD shows exceptional photoelectric performance, featuring a high photo-to-dark current ratio of 1611, a large responsivity of 48.43 mA/W, and rapid rise and decay times of 261 ms and 890 ms, respectively, without any external power supply. Incorporating the Cu2O interface layer results in notable enhancements in responsivity and detectivity compared to the heterojunction without the Cu2O layer. This improvement is attributed to heterojunction interface contact, energy band engineering, and the tunneling effect. The Cu2O layer expands the depletion zone and promotes charge separation. Due to its thinness, charges can tunnel through the Cu2O layer from one metal electrode to another. Furthermore, the interfacial Cu2O layer can alter the valence band offset and the conduction band offset of the p-CuI/n-MgZnO junction, enhancing carrier transport between MgZnO and CuI. These results lay the groundwork for using self-powered MgZnO-based heterojunction photodetectors in light-based devices in the future. They also demonstrate the potential of designing novel heterojunctions to create high-performance self-powered PDs for UV detection.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"5 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These defects are often accompanied by large amounts of background texture information. Especially, some defects with the low resolution and small size are prone to false alarms and missing detections. Aiming to address the issues of these specific defects, this paper proposes a bidirectional cross-scale feature fusion network combined with non-stridden convolution for steel surface defect detection. First, to improve the model’s inference speed and reduce the number of parameters, a simple yet effective convolution (PConv), the core component of FasterNet, is introduced in the feature extraction module instead of the traditional ResNet operator. Second, the bidirectional crossing (BiC) module is embedded to construct a bidirectional cross-scale feature fusion network (BiCCFM), which provides more accurate localization clues to enhance the feature representation on small targets. Finally, combined with non-stridden convolution, the SPD-Conv module is developed to aggregate the detection performance of small targets in low-resolution images. Comprehensive experimental results on the public NEU-DET dataset validate the effectiveness of the embedded modules and the proposed model. Compared with other state-of-the-art methods, the proposed model achieves the best accuracy (74.2% mAP @ 0.5) while maintaining a relatively small number of parameters.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"27 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143526162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, accurately reconstructing 3D shapes is particularly challenging when dealing with objects with specular reflective surfaces. To address this problem, this paper proposes an innovative multi-stage deep learning method that combines the pix2pix adversarial network and a modified version of the DC-HNet architecture. The technique aims to accurately reconstruct 3D shapes from streaked images by eliminating highlights in specular reflection regions through a staged process first. Specifically, the pix2pix adversarial network is first used to eliminate highlights and generate streak images without specular reflections; subsequently, the improved DC-HNet network is further processed to accurately deduce the phase distribution information of the object from the streak images with the elimination of highlights, and then reconstruct the 3D shape. Compared with the traditional self-encoder-based convolutional neural network (CNN) model, the multi-stage approach proposed in this paper significantly improves the accuracy of 3D shape reconstruction by separating the two key steps of highlight elimination and phase derivation and combining them with multi-scale feature enhancement. In this paper, the method’s effectiveness is verified on experimental data, and the results show that the proposed method provides a significant improvement in 3D shape prediction accuracy compared with the existing U-Net network and MultiResUet network. These findings not only demonstrate the innovation and robustness of the proposed method but also show its potential in scientific research and engineering applications.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"80 1 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143427311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This structure is suitable for various applications such as digital signage or entertainments with illusion. If rotational perception like hollow face illusion would be obtained by simple aerial images like simple illustrations, application zone could be expanded to various field, such as animation or marks.

A broadband polarization filter and a temperature sensor can be achieved based on the same simple PCF structure, with a hollow core separately filled with liquid crystal and toluene. The polarization filtering and sensing properties of the proposed PCF were studied using the finite element method (FEM). Numerically results show that variations in the diameter of both the liquid crystal-infiltrated central hole and the cladding air holes have a slight effect on the polarization filter characteristics. The polarization filter can be effectively tuned in terms of the central wavelength, crosstalk, and bandwidth by adjusting the thickness of the gold film. The proposed PCF polarization filter with t = 22.5 nm has achieved a wide bandwidth of 1850 nm across wavelengths ranging from 1.2 to 3.05 μm for a fiber length of 50 μm, achieving a high value of polarization loss ratio (PLR) of 28,717 at λ = 1.31 μm with losses of 1723 dB/cm for y-polarization and 0.06 dB/cm for x-polarization. The y-polarized core mode in this design with t = 10 nm is rapidly attenuated, experiencing losses larger than 1340 dB/cm over wavelengths ranging from 1.9 to 3.0 μm; it also exhibits a bandwidth of 2200 nm with crosstalk greater than 20 dB when using a fiber length of 50 μm at wavelengths above 1.5 μm. Furthermore, a temperature sensor that utilizes toluene as its core material exhibits a consistent average sensitivity of 6.68 nm/°C for y-polarization and can detect temperatures ranging from − 10 to 40 °C. The sensor maintains stable sensitivity within ± 1% fluctuation of the gold film thickness in the sensing range of − 10 to 40 °C.","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"62 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143375148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
