本文对基于“模态控制”原理的折射菲涅耳透镜设计进行了实验和理论研究。与类似的单孔径（6 mm）透镜的性能比较表明，该菲涅耳透镜可以获得更高的光学功率（3屈光度以上）。提出了一种组合控制方式，以优化其在不同焦距下的运行。理论建模证明了通过优化驱动技术进一步改善其像差的可能性。
We present the experimental and theoretical study of a refractive Fresnel lens design based on the “modal control” principle. Comparison of its performance with a similar but single aperture (6 mm) lens shows that the suggested Fresnel lens can achieve higher optical powers (above 3 diopters). A combined control mode is suggested to optimize its operation for different focal ranges. Theoretical modeling demonstrates the possibility of further improvement of its aberrations by means of an optimized driving technique.
