曲面复眼成像系统的研究

研究了两种曲面复眼成像系统,并首次将曲面场镜阵列引入曲面复眼成像系统,使其边缘视场的成像质量进一步提高,视场角进一步加大。进行了成像系统的建模以及光线追迹,两种结构的视场角分别达到60°和88°,整个系统的体积分别为0.9 mm×0.9 mm×0.5 mm和0.9 mm×0.9 mm×0.75 mm。文中给出了用激光直写设备在曲面基底上进行光刻来制作曲面微透镜阵列的方法。

Study on curved compound eye imaging system

Two kinds of curved compound eye image systems were studied. It is the first time that a curved field lens array was introduced into the curved compound eye image system to improve the image quality of the marginal Field of View(FOV) and enlarge the FOV. The model of a image system was designed and the ray trace was completed based the software LIGHTTOOLS. The FOVs of the two systems are 60° and 88°; the volume are 0.9 mm×0.9 mm×0.5 mm and 0.9 mm×0.9 mm×0.75 mm,respectively. The lithography technique to fabricate the curved microlens array on the curved substrate by using laser direct writing system was also given.
