Athermalization of an Optical System Based on Lens Shape and Assembly Method
Sihua Xu,Xiaoqiang Peng,Guipeng Tie,Chaoliang Guan,Hao Hu,Yupeng Xiong 한국광학회 2019 Current Optics and Photonics Vol.3 No.5
Temperature adaptability is an important metric for evaluating the performance of an optical system. The temperature characteristics of the optical system are closely related to the material and shape of its lens. In this paper, we establish a mathematical model relating the temperature characteristics to the shape and material of the lens. Then a novel assembly structure that can solve the lens constraint and positioning problem is proposed. From those basics, the correctness of the theoretical model and the effectiveness of the assembly structure are verified through simulated analysis of the imaging quality of the optical system, whose operating temperature range is -60~100°C.

Calculation of Effect Ratio of 21 Geometric Errors and Detection of Surface Figure Error
Tao Lai,Xiaoqiang Peng,Guipeng Tie,Can Yang 한국정밀공학회 2021 International Journal of Precision Engineering and Vol.22 No.4
Traditionally, a machine tool is regarded as a rigid-multi body system, and it is studied by integrated geometric error modeling. Considering a three axis-machine, this study introduced the ratio and effects of the geometric errors on the surface figure error. First, based on synchronous iteration location, a surface matching model was employed to assess the coordinate measurement result. Subsequently, considering all the geometric error functions having the same parameters, the effect ratio and the surface figure error of a single geometric error were obtained. Concurrently, based on the effect ratio and surface figure error results, the main geometric errors were obtained, such as EZX, EZY, EAX, and COY. Moreover, the proposed method and the main errors were experimentally verified. By compensating the main errors, the sphere accuracy was improved by 53.4% and the flat accuracy by 70.0%. Additionally, the method proposed in this paper could be utilized to detect the surface figure error.

Design and Manufacture of High Accurate Aerostatic Guideway with Glass Material
Tao Lai,Xiaoqiang Peng,Meng Guo,Guipeng Tie,Chaoliang Guan,Junfeng Liu,Aihua Chen 한국정밀공학회 2019 International Journal of Precision Engineering and Vol.20 No.6
Universal materials such as metal and marble are applied for aerostatic guideway. However, metal or marble guideway is usually manufactured by traditional turning and grinding. The corresponding geometric error, load and stiffness of the guideway are limited by the accuracy of traditional manufacture. Glass guideway can be measured by the optical method, thereby improving the performance. This paper presents a guideway designed and manufactured with the K9 glass. The guideway is manufactured by computer controlled optical surfacing and magnetorheological finishing. Moreover, the optical measurement is applied to measure the flatness and the geometric error of the guideway. Besides, the slider on the guideway is designed based on orifice compensated. The working surface error of the guideway is less than 0.1 μm, and the gas film is smaller than traditional aerostatic bearing. Therefore, the load and stiffness of the aerostatic sliders are higher than the traditional slider. Additionally, the effects of configuration and load onto the accuracy of guideway are introduced. The motional geometric error is measured after assembling, with the results that the pitch is better than 0.4 arcsecs and the yaw is better than 0.9 arcsecs. Furthermore, the straightness is compensated at 50 nm/200 mm. At last, the guideway is applied for an ultra-precision profilometer, and a flat is measured by the profilometer, giving 0.1 μm repeatable flatness.

Design and experimental demonstration of coaxially folded all-reflective imaging system
Yupeng Xiong,Yifan Dai,Shanyong Chen,Guipeng Tie 한국광학회 2019 Current Optics and Photonics Vol.3 No.3
With slimmer, lighter and all-reflective imaging systems in high demand for consumer and military applications, coaxially folded optical image systems are widely considered because they can extend focal length and reduce track length. Most of these systems consist of multiple surfaces, and these surfaces are machined on one element or grouping processing on two elements. In this paper, we report and first experimentally demonstrate an all-aluminum all-reflective optical system which consists of two optical elements, with two high order aspherical surfaces in each element. The coaxially folded system is designed with Seidel aberration theory and advanced optimization with Zemax. The system is made of all-aluminum material processing by single point diamond turning (SPDT). On this basis, we completed the system integration and performed an imaging experiment. The final system has the advantages of short track length and long focal length and broad application prospects in the micro-unmanned aerial vehicle field.
