摘要

传统的眼镜镜片设计方法主要依赖于柯丁顿方程或经典的优化算法,其复杂性高、效率低。本文提出了一种基于可微光线追踪(DRT)的高效镜片设计方法,该方法通过自动微分计算价值函数对镜片表面参数的偏导数。一个-12D透镜的设计表明,该方法在优化效率、边缘厚度和平均功率误差方面优于传统的优化方法,包括模拟退火(SA)、粒子群优化(PSO)和遗传算法(GA),同时与SA和PSO相比实现了更低的畸变。此外,我们还探讨了顶点距离变化对设计结果的影响,以及优化透镜的空间分布与畸变和平均功率误差的关系。

Spectacle lens design with double aspheric surfaces using differentiable ray tracing.

Traditional spectacle lens design methodologies have been hindered by their high complexity and low efficiency, primarily due to their reliance on Coddington equations or classical optimization algorithms. We propose an efficient spectacle lens design method based on differentiable ray tracing (DRT), where the partial derivatives of the merit function with respect to the lens surface parameters are computed through automatic differentiation. A -12D lens design demonstrates that the proposed method outperforms traditional optimization approaches, including simulated annealing (SA), particle swarm optimization (PSO), and genetic algorithm (GA), in terms of optimization efficiency, edge thickness, and mean power error, while achieving lower distortion compared to SA and PSO. Additionally, we explored the impact of vertex distance variation on the design results, as well as the spatial distribution of optimized lenses in relation to distortion and mean power error.
