Displacement encoder using sine micro-window grating (1999)
Journal Article
Wang, C., Ma, X., Zhang, G., & Guo, S. (1999). Displacement encoder using sine micro-window grating. Acta Optica Sinica, 19(8), 1153-1157

A novel displacement encoder, employing a sine micro-window grating and featuring high quality signals free from harmonic errors, was developed. The sine micro-window grating is a special component composed of arrays of micro-elements with a sine win... Read More about Displacement encoder using sine micro-window grating.

A subdivision-based implementation of non-uniform local refinement with THB-splines
Presentation / Conference Contribution
Li, Q., Ma, X., Cripps, R., & Lin, P. A subdivision-based implementation of non-uniform local refinement with THB-splines

Paper accepted for 15th IMA International Conference on Mathematics on Surfaces, 2017. Abstract: Local refinement of spline basis functions is an important process for spline approximation and local feature modelling in computer aided design (CAD). T...
