摘要
当前的光电侦察领域设备不断地向轻、小型化发展,而传统变焦光学系统的体积与质量往往达不到微小型光电侦察平台的载荷要求,因此小型无人机等侦查平台只能搭载定焦镜头,制约了分辨率与侦查距离的提升,限制了侦查能力。液态透镜技术利用单片透镜即可实现透镜焦距的调节,大大减小了光学系统的体积,且其变焦响应速度快、变焦范围大,由液态透镜组合的光学系统可以在固定的小体积内实现快速变焦,在军民领域都有广阔的应用前景。该文对前人的理论基础与研究方法进行了调研与综述,简述了液态透镜的5种基本原理,并分析了各自的特点,分别介绍了国内外液态透镜的研究现状,指出了不同液态透镜的优缺点及未来的发展与研究方向。
At present, the equipment in the field of photoelectric reconnaissance develops lighter and smaller constantly, while the volume and weight of traditional zoom optical system cannot satisfy the load requirements of micro photoelectric reconnaissance platform. Therefore, the small unmanned aerial vehicle(UAV) and other reconnaissance platforms can only equip withprime lens, which limits the improvement of resolution, detection distance and reconnaissance ability. The liquid lens technology can adjust the focal length by using a single lens, which largely reduces the volume of the optical system, and has fast zoom response and wide zoom range. The optical system composed of liquid lens can fast zoom in a fixed small volume, which has broad application prospects in both military and civil fields. The theoretical basis and research methods of the predecessors were investigated and summarized. Firstly, five basic principles of liquid lens were briefly described, and their characteristics were analyzed respectively. Then, the research status of liquid lens at home and abroad were introduced. And finally, the merits and demerits of liquid lens, as well as its future development and research directions were indicated.
