英文摘要	The angular displacement measurement technology based on image detector is a hot research to realize high-precision and high-resolution angular displacement measurement. In order to improve the robustness of the angular displacement measuring devices, a high precision image displacement measurement device with self-adaptive installation techniques is designed in this paper. The installation and adjustment processes are very simple, and high resolution and high precision measurement output can be guaranteed in the presence of eccentricity in the calibration grating. Firstly, the angle measurement device using dual linear imaging sensors is proposed and a single-ring absolute grating is designed. Then, a high-resolution subdivision algorithm based on a centroid algorithm is used to subdivide the image, and dual linear image sensors are used to compensate for the angle measurement error. Finally, an experimental device is designed to test the performance of the adaptive installation. Experiments show that when the eccentricity of the grating is within 1 mm, the designed device can achieve highly precise angular displacement measurements with high resolution. The device designed in this paper guarantee the output accuracy when the grating has an installation eccentricity of 1 mm, which lays a foundation for improving the adaptability of small angular displacement measuring devices. 2020, China Science Publishing & Media LTD.
