摘　　要：针对各种类型的Fresnel透镜的设计方法,从弧形基面Fresnel透镜的结构设计出发,通过对不同楞型条件的推导,从而获得能够适应各种类型Fresnel透镜结构设计的统一的设计公式。并据此,提出了Fresnel透镜效率计算方法,对目前常用Fresnel透镜的光学效率进行分析对比,对其适用性和优缺点作了定性评价。A general design formula for the Fresnel lens is obtained through a simple deduction which is initially based on an optical model for the design of the Fresnel lens with a curved base.A method to calculate optical efficiency of the Fresnel lens is brought forward and the comparisons are made between different shapes Fresnel lens which are commonly used now.The qualitative evaluation of their adaptability,the advantages and the disadvantages has finally been done in this paper.
