基于对称积分成像系统，提出了一种平面大口径成像云台系统。所提出的系统包括五个透镜阵列和两个致动器。通过使用两个致动器移动位于入射侧的两个透镜阵列来执行图像平移-倾斜功能。两个透镜阵列的位移小于一个透镜间距;因此，可以在短时间内执行平移-倾斜功能。此外，通过增加透镜阵列中的透镜数量，可以容易地扩大所提出的平移-倾斜系统的光学孔径。所提出的技术进行了实验验证，使用放大模型。
An image pan–tilt system with a flat shape and a large aperture is proposed based on a symmetric integral imaging system. The proposed system comprises five lens arrays and two actuators. The image pan–tilt function is performed by shifting the two lens arrays located at the entrance side using two actuators. The displacements of the two lens arrays are less than one lens pitch; hence, the pan–tilt function can be performed in a short time. Moreover, the optical aperture of the proposed pan–tilt system can easily be enlarged by increasing the number of lenses in the lens arrays. The proposed technique is experimentally verified using a scaled-up model.
