Special Issue Information

Dear Colleagues,

Symmetry plays a fundamental role in optoelectronics, influencing light propagation, optical field manipulation, and photonic device design. In light–matter interactions, symmetry and its breaking (such as in chiral structures) can induce complex optical phenomena, including nonlinear effects, polarization control, and optical rotation. In photonic crystals and resonators, structural symmetry dictates light propagation modes, photonic band structures, and bandgaps. In topological photonics, symmetry governs the existence and protection of photonic edge states, enabling defect-free, lossless transmission. Asymmetric or chiral designs can lead to unconventional optical effects such as birefringence and enhanced plasmonic resonances, with broad applications in sensing, communication, and quantum optics. This Special Issue explores recent advances in symmetry and symmetry breaking in optoelectronics and their impact on the functionality, performance, and design of optoelectronic devices.

This study addresses the challenging issues in 3D point cloud feature matching within the field of computer vision, where high data quality requirements and vulnerability to disturbances significantly impact performance. Existing methods are prone to outliers when generating feature correspondences due to noise, sampling deviations, symmetric structure, and other factors. To improve the robustness of point cloud feature matching, this paper proposes a novel 3D spatial encoding (3DSE) method that incorporates compact geometric constraints. Our method encodes the spatial layout of matching feature points by quantifying the order of appearance of matching points, and combines rigidity constraints to iteratively eliminate the least consistent matching pairs with the remaining point pairs, thereby sorting the initial matching set. The 3DSE algorithm was evaluated on multiple datasets, including simulated data, self-collected data, and public datasets, which cover data from both LiDAR and Kinect sensors. The comparison results with existing techniques demonstrate that 3DSE exhibits superior performance and robustness in handling noise, sparse point clouds, and changes in data modalities. The application of the proposed method significantly enhances the point cloud registration process, showing promising potential for 3D reconstruction, model-driven 3D object recognition, and pose estimation of non-cooperative targets.

As a typical representative of advanced remote sensing imaging technology, the segmented interferometric array integrated optical imaging system has problems such as poor contrast, insufficient medium and low-frequency information, and low resolution in its imaging quality. In this paper, based on the multi-dimensional light field conversion model of the integrated optical imaging quality of the full-link segmented interferometric array, the spatial distribution of the multi-baseline lens array is researched. The design of the hierarchical non-uniform sampling lens array, which is symmetrical in spatial distribution, is proposed. Combined with the actual production and processing, the influence of the fill factor of the lens array on the imaging quality is analyzed, and the tolerance error for the fill factor of the lens array is 10%. The research results can provide a theoretical basis for the optimal design and fabrication of the segmented interferometric array integrated optical imaging system. Full article
