Abstract
En 中文
• Idealized Modeling via Randomized Optical Power Allocation. The method abstracts physical lenses into zero-thickness ideal optical elements. By randomly assigning optical power and spacing to the first N-1 elements, it reduces variables and rapidly generates initial structures meeting focal length and BFL constraints. • Optimization Strategy Using Ray Deflection Angle-Based Objective Function. A loss function is constructed from cumulative deflection angles of marginal and chief rays at each surface. This approach intrinsically connects to Seidel aberration theory, guiding the search for low-aberration configurations. • Automated Workflow Integrating MATLAB and CODE V. An interconnected framework between MATLAB and CODE V enables closed-loop optimization. The process completes initial structure generation and physical realization within 5 minutes, significantly improving design efficiency.
