In order to achieve high-quality imaging while simplifying the structure and reducing the size of the optical system, a miniature dual-disc folding reflection optical system was designed. A design approach incorporating reflector fitting is employed;the adjacent reflector is fitted to one mirror. The optimized optical system contains two mirrors, and the system length-to-focal-length ratio is 0.325, which significantly reduces the axial distance of the system. Furthermore, the engineering of the optical system was successfully achieved. The experimental results demonstrate that the captured images display consistent clarity, are free from distortion, and meet the specified design requirements. (c) 2024 Optica Publishing Group.

Precise spatial manipulation of particles via optical forces is essential in many research areas, ranging from biophysics to atomic physics. Central to this effort is the challenge of designing optical systems that are optimized for specific applications. Traditional design methods often rely on trial-and-error methods or on models that approximate the particle as a point dipole, which only works for particles much smaller than the wavelength of the electromagnetic field. In this work, we present a general inverse design framework based on the Maxwell stress tensor formalism capable of simultaneously designing all components of the system while being applicable to particles of arbitrary sizes and shapes. Notably, we show that with small modifications to the baseline formulation, it is possible to engineer systems capable of attracting, repelling, accelerating, oscillating, and trapping particles. We demonstrate our method using various case studies where we simultaneously design the particle and its environment, with a particular focus on free-space particles and particle-metalens systems.

Learning-based wide-angle optical design distortion optimization for improved monocular depth estimation

As most cameras are currently built to be used alongside machine learning algorithms, image quality requirements still emanate from human perception. To redefine key performance indicators (KPI) for machine vision, optical designs are tested and optimized before their conception using differentiable simulation methods and gradient backpropagation to jointly train an optical design and a neural network. Although this helps to design optical systems for improved machine learning performance, it remains unstable and computationally expensive to model complex compound optics such as wide-angle cameras. We focus on optimizing the distortion profile of ultra wide-angle designs as it constitutes the main KPI during the optical design. Along the way, we highlight the benefits of controlling the distortion profile of such systems, as well as the challenges related to using learning-based methods for optical design.

IEEE SENSORS JOURNAL 2025年第2期25卷 2646-2657页

作者： Deng, Yongqiang Jiang, Jin Univ Western Ontario Dept Elect & Comp Engn London ON N6A 5B9 Canada

This article presents design, analysis, and experimental validation of a novel multipoint optical fiber sensor (OFS) probe of high spatial resolution. The probe incorporates an innovative interlaced thermal conductor-insulator-conductor (CIC) architecture to mitigate effects of thermal smearing that often occurred with the sheath in existing probes. This design ensures minimal thermal resistance between the sensor elements and the measurement environment. The design is backed by a detailed thermal analysis and computer simulation. Three prototype probes are constructed and tested in realistic environments to validate the design concept and evaluate the probe performance in transient and steady-state conditions. The results have confirmed unequivocally the unique features of this design and superior performance in achieving high spatial resolution in simultaneous measurements of localized temperatures in nonuniformly distributed thermal fields.

PRECISION engineering-JOURNAL OF THE INTERNATIONAL SOCIETIES FOR PRECISION engineering AND NANOTECHNOLOGY 2025年 94卷 545-570页

With the rapid development of optical technology, opto-mechanical systems are widely applied in space exploration, high-energy laser applications, and ultra-precision laser processing and measurement. The precise assembly of optical components is a key factor in ensuring the performance of opto-mechanical systems. Therefore, improving the assembly performance of optical systems has become one of the hot topics in optical research. The research on the assembly performance of existing opto-mechanical systems primarily emphasizes predictive model construction, optimization of structural stiffness, assembly process planning, and automation equipment development. These studies typically address only one or a few specific issues and lack a systematic review of the overall development status and technical interrelations of high-performance assembly technologies for opto-mechanical systems. Moreover, technology that integrates "design, assembly, measurement, and adjustment" to enhance optomechanical systems has yet to be developed. Centered on two key performance metrics of opto-mechanical systems-pointing accuracy and surface distortion, this paper reviews the theoretical frameworks and technical progress of related predictive models, addressing three aspects: current research status, error analysis, and quantitative performance description methods. Secondly, from the perspectives of optimization design and adjusting processes, this paper summarizes the main technical approaches for improving optical performance, comparing, and applying deterministic and uncertainty optimization methods for optical system error factors, and analyzes their applicability and limitations. Subsequently, this paper focuses on the development status of intelligent assembly and adjustment technologies and analyzes their role in improving assembly accuracy from two aspects: assembly processes and assembly equipment. Finally, this paper concludes by summarizing the findings and envisioning future d

design method for engineering the initial structure of a spectrometer

引用

APPLIED OPTICS 2024年第7期63卷 1783-1793页

A well-considered initial structure plays a key role in the design of an exceptional spectrometer. Previously, the design method for the optical initial structure (MOIS) that has only focused on the optical properties based on simple imaging formulas and coma-free conditions has been extensively researched. However, as the shape and size of any optical component are not considered for the MOIS, the optical parameters before and after optimization are very different, which results in a loss of reference value of the initial structure. In order to address the aforementioned issues, a more efficient design method for engineering initial structure (MEIS) of the spectrometer is proposed, where not only the above optical properties are considered but also the relative position and size of any optical component in order to avoid the interference between the optical components. For the MEIS, three important anti-interference conditions between components are deduced through ray tracing, and the relevant imaging formulas are derived by geometric optics, which leads to the rapid calculation of component parameters and the acquisition of an initial structure satisfying the corresponding design requirements by setting reasonable spacing margins. To verify the validity of the MEIS, a wide-band high-resolution spectrometer system with a large CCD Toucan 216 is designed within a wavelength range of 700-1000 nm and a resolution of 0.5 nm. Compared with the MOIS, the positions of each component in the MEIS are more rationalized, which significantly eliminates the complex optimization processes. For the MEIS, changes only in the position of the image plane occur with minimal variations in the axial and vertical wheelbase (less than 0.5 mm) as well as the deflection angle (only 0.5 degrees), with favorable evaluation indices. The MEIS has an important reference value for the rapid and efficient design of excellent spectrometers. (c) 2024 Optica Publishing Group

IEEE ACCESS 2025年 13卷 18510-18523页

With the development of digital optical systems, the industry quality requirements for optical lenses are becoming higher. A design method for optical lens assembly based on star point bonding and a method for surface shape accuracy are proposed in response to the development of digital optical systems and the continuously improving quality requirements of the optical lens industry. The study adopts the three-point support principle to bond optical lenses, thereby optimizing the assembly process of optical lens components. Finite element analysis is conducted on the lens assembly process using computer-aided engineering software to ensure accuracy and reliability of the assembly. In addition, the matching technique is used to analyze the surface shape error of the lens, further improving the control technology of surface shape accuracy. Compared with traditional binding and ring pressing methods, the research method improved assembly accuracy by at least 30%, significantly reducing stress concentration caused by uneven tightening, and effectively avoiding deformation of optical lenses during processing and assembly. In addition, the surface shape accuracy analysis method was about 50% faster than traditional methods. At the same conditions, the calculation error was reduced by an order of magnitude. These improvements not only improve the assembly accuracy and work efficiency of optical lenses, but also provide strong technical support for the production of optical lenses.
