Abstract
A method is proposed to measure off-axis aspherical mirrors with a circular flat base,a rectangular flat base and a family of parallel lines that cut the circular flat base by a coordinate measurement machine(CMM).In response to the base features above,workpiece coordinate system is designed,and the positioning points used to establish the workpiece coordinate system are defined.The 3D-coordinates point-cloud data on the off-axis mirrors are obtained with automatic measurement of single points schema by CMM,and then,the off-axis aspheric surface data processing model for these error corrections is built.Compared with the data by the theoretical model,the surface error of an actual off-axis aspheric surface is obtained.All the pre-polishing processes are guided according to the measurement results.

期刊介绍:
The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months.
The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
