"High resolution angular displacement sensor development and industrialization" (2017 yff0105300) project is YuHeng optical clamping of the "high precision, high resolution absolute rotary encoder grating enhancement" and "high integrated single code word absolute type grating ruler r&d and industrialization of" two countries "twelfth five-year" science and technology major projects successfully completed after the third national scientific research and special tasks. This project joint institute of Chinese Academy of Sciences changchun optical precision machinery and physical, jilin university, changchun university of science and technology, heavy loose where the robot automation co., LTD., and shen machine group, kunming machine tool co., LTD. Jointly undertake, time frames for July 2017 to June 2020.
YuHeng optical according to project requirement development with independent intellectual property rights, the Angle measurement resolution (resolution) 28; Precision is 1.07 "(accuracy); Packaging size 100 mm x 25 mm; Refresh rate acuity 8 KHZ; Impact resistant ability to 60 gb or more, the average time between failures of 20000 hours or more stable and reliable quality, the accuracy of precision instruments and meters position feedback, position detection, automatic control, the servo system products, etc. Since this project is carried out formally since July 2017, in order to ensure the orderly implementation of projects, the company strictly implement science and high technology research and development center, has listed the project started, scheme evaluation, a key indicator, technology exchange meeting, senior senior expert group set up to "appointed a committee of experts with special do the responsibility of the appointed experts, for the implementation of the project to the supervision and evaluation, avoid technical risk in advance, agreed to provide important technical support for the project.
