变焦镜头的智能化设计方法研究

A systematic study is conducted on the intelligent computer-aided design (ICAD) of zoom optical systems. The emphases of the study are placed on key technical problems such as the first-order design for zoom lenses with multiple moving groups, the automatic generation of zoom lens initial constructions, and the optimization of image quality. A new computable method of determining Gaussian parameters is proposed, in which the cam curves are optimized with the numerical aperture of each lens group constrained to a rational value. A mechanism is established for the automatic addition and deletion of optical elements during the course of lens optimization. Related features are implemented in the GOLD software developed under the continuous support of the National Natural Science Foundation of China, which can now realize the ICAD for various types of zoom lenses and multi-configuration systems. The software is widely used in China, and it plays an important role in the design and development of new products such as zoomable stereo microscopes by the Chinese optical industry.
