Layout model and analysis of annular subaperture stitching technique for testing large aspheric mirror;

Based on the idea of inverse solution on the error elimination, the DFP multi-dimensional variable scale algorithm are applied on the surface shape’s error analysis of ultra-precision high-order aspheric lens.

The optical design of optical prism with aspheric lens for fingerprint identification is researched.

A new form generation method for ultra-precision axisymmetric aspheric mirrors is introduced.

The automatic placement of an aspherical lens in front of a fibre-scope depends on the working distance.

Radius of curvature is an important parameter in machining and measuring aspherical mirrors and in optical alignment.
