摘要

This paper presents a new method for analyzing ghost paths for camera lens design using a method that predefines ray orders and uses cloud-based parallel processing. Our method enables comprehensive ghost analysis of complex optical systems with multiple reflections, which were previously considered computationally impractical. The performance evaluation demonstrated the successful processing of over 4.4 billion rays through complex optical paths, completing calculations within practical time constraints.
