The modernism art spirit mainly manifests in four aspects: firstly,it denies the realism tradition,from "mirror" to "non-mirror";secondly,it denies romanticism tradition,from "lamp" to "non-lamp";thirdly,i.

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.

Active passive mode locking was observed in Nd∶YLF laser when one of the mirror was replaced with a nonlinear mirror which composed of CLBO crystal and a dichroic mirror.
