六、内容简介：

Freeform and Structured Surfaces are complex surfaces that possess non-rotational symmetry while different dimensional scales of structured patterns are embedded in large-scale flat or curved substrates. They are widely used in advanced applications such as compound eye lenses for 3D imaging, lobster eye focusing optical systems for X-ray detection, and surfaces with self-cleaning ability and wettability, which are indispensable with specially designed functional multi-scale structured surfaces in order to maximize the performance of products. Due to the geometrical complexity of these surfaces, they have to be fabricated by more than one type of ultra-precision machining technology with high precision in terms of sub-micrometre form accuracy and nanometric surface finishing so as to ensure the functionality of the components. Moreover, many measuring principles and instruments have also been proposed and developed to cover a wide measurement range with respect to specific and varying metrological needs. In this presentation, the state-of-the-art research on ultra-precision machining and measurement of freeform and structured surfaces is discussed. Some of the case studies of applications of freeform and structured surfaces   are discussed. The presentation attempts to shed some light on the future development of machining and measurement of freeform and structured surfaces which will help spur the growth in the application and manufacturing of these surfaces.
