基于蒙特卡洛的手机变焦镜头设计
Monte Carlo based smartphone zoom lenses design
摘要
Abstract
With the advancement of consumer electronics,there is an increasing demand for high-perfor-mance,miniaturized zoom lenses.In zoom lenses,the distribution of optical power among components and their zoom cam curve-collectively known as first-order configurations-significantly influence imaging performance.However,selecting optimal first-order configurations is challenging through simple analyti-cal methods,thereby complicating the design of lightweight zoom lenses.To globally assess the potential performance of first-order configurations in zoom lenses and explore design methodologies for lightweight zoom lenses,this study employed a Monte Carlo search algorithm to identify optimal first-order configura-tions.Initially,focal lengths for each component were generated based on the Monte Carlo method,and configurations satisfying the zoom constraint equations were filtered.Subsequently,lens design files were created for the valid configurations,followed by ray tracing and rapid optimization to evaluate perfor-mance,ultimately selecting configurations with superior optical power distributions.Finally,taking a smartphone zoom lens as an example,a compact zoom lens was designed using the high-performance con-figuration as the initial structure.This lens maintained a constant F-number of 2.9,achieved an equivalent focal length range of 61-183 mm,and had a total track length of 90 mm.It featured smooth zoom cam curve,modulation transfer function(MTF)values exceeding 0.45 at 80 lp/mm and 0.15 at 160 lp/mm across all fields of view and focal lengths,distortion below 4%,and relative illumination above 20%.Compared to conventional zoom lenses,it offered significant advantages in terms of weight reduction.The design results demonstrate the effectiveness of the proposed method,which combines Monte Carlo-gener-ated first-order configurations with ray tracing evaluations,providing a novel approach for designing com-pact zoom lenses.关键词
