摘　　要：提出了分段环形曲面的面型描述及设计方法。提出了一种从非球面到分段环形曲面的高精度转换方法来建立初始曲面,并讨论了分段环形曲面的优化策略、实现方法和约束条件。将所设计的分段环形曲面应用于一款超短焦投影物镜的设计和优化中,优化后的系统总长仅为155mm,最大畸变仅为1.36%。研究结果表明,该新型曲面可以提高光学系统设计的自由度和灵活性。The surface description and design methods of annularly piecewise surfaces are proposed.A high-precision transformation method from aspherical surface to annularly piecewise surface is proposed to construct an initial surface,and the optimization strategies,constraints and implementation methods for the annularly piecewise surface are discussed.This proposed surface is employed to design and optimize an ultra-short projection lens.The total length is 155 mm and the maximum distortion is 1.36% after optimization.The research results indicate that this annularly piecewise surface can improve the freedom and flexibility of optical design.
