本文提出了一种在曲面基板上以一种新的结构排列微透镜的微透镜阵列。所提出的MLA微透镜按度数非均匀排列，并遵循等差数列规律。介绍了详细设计方法，并给出了设计实例。建立了相应的模型，并与均匀排列微透镜的曲面微透镜阵列模型进行了比较。采用近轴射线追踪法对两种不同模型的焦面进行了观测。结果表明，本文提出的结构更紧凑的微透镜阵列具有平面焦面，与市面上现有的图像传感器兼容。此外，它还具有较高的填充系数，更适合于仿生复眼的制造。
Micro lens array with micro lenses arranged in a new configuration on a curved substrate is proposed in this paper. The micro lenses of the proposed MLA are arranged non-uniformly by degree with which followed a law of arithmetic sequence. Detail design method is introduced and a design example is given. The corresponding model is constructed and compared with that of the curved micro lens array with micro lenses arranged uniformly. Paraxial ray-tracing method is used to observe the focal surface of the two different models. It is concluded that the micro lens array with more compact construct proposed in this paper has a plane focal surface so that it is compatible to the commercial available image sensor. In addition, it has a higher filled factor and more suitable for the fabrication of bionic compound eye.
