Paper Abstract

Freeform has been widely applied in both imaging optics and non-imaging optics. Optical freeform surfaces can be fabricated by ultra-precision machining process. The geometrical errors of these freeform optics can be measured by contact or non-contact approaches. Imaging quality is one of the major criteria for imaging optics, while illumination distribution and energy efficiency are the important performance parameters for non-imaging optics. It is necessary and helpful to relate the geometrical errors and the optical performance of the freeform optics, so as to provide a well balance between the machining accuracy and efficiency. This paper surveys the current research on the relationship between optical performance and geometrical errors of optical surfaces, including the research work for the measurement of geometrical errors of freeform surfaces, and the valuation of optical performance. It shows that there is still a lack of research work undertaken to quantitatively analyze the relationship between the optical performance and geometrical errors. Therefore, it is interesting to carry out some future work on the quantitative analysis of the relationship between specific optical parameters and certain frequency surface errors.
