This review presents a systematic perspective on the development of micro-optofluidic lenses. The progress on the development of micro-optofluidic lenses are illustrated by example from recent literature. The advantage of micro-optofluidic lenses over solid lens systems is their tunability without the use of large actuators such as servo motors. Depending on the relative orientation of light path and the substrate surface, micro-optofluidic lenses can be categorized as in-plane or out-of-plane lenses. However, this review will focus on the tunability of the lenses and categorizes them according to the concept of tunability. Micro-optofluidic lenses can be either tuned by the liquid in use or by the shape of the lens. Micro-optofluidic lenses with tunable shape are categorized according to the actuation schemes. Typical parameters of micro-optofluidic lenses reported recently are compared and discussed. Finally, perspectives are given for future works in this field.
本综述从系统的角度介绍了微流控透镜的发展。通过最近文献中的示例来说明微流控透镜的发展进展。与使用诸如伺服电机等大型致动器的固体透镜系统相比,微流控透镜的优势在于其可调谐性。根据光路和基底表面的相对方向,微流控透镜可分为面内或离轴透镜。然而,本综述将重点介绍透镜的可调谐性,并根据可调谐性的概念对其进行分类。微流控透镜可以通过使用的液体或透镜的形状来进行调谐。具有可调谐形状的微流控透镜根据致动方案进行分类。最近报道的微流控透镜的典型参数进行了比较和讨论。最后,对该领域的未来工作提出了展望。
