摘要
相比于传统的机械变焦镜头,液体变焦镜头具有体积小、响应快、成本低和集成度高等特点,被广泛应用于图像采集、目标追踪和特征识别等领域。焦距调节方式决定了液体镜头的性能和应用,本文概括了基于液晶材料、介电泳、电化学、电润湿原理的物性控制式变焦镜头和基于静电力、电磁力、压力调节和环境响应的机械驱动式变焦镜头的研究现状,介绍了液体变焦镜头在光流控芯片内的集成应用,并指出当前面临的主要问题和解决方案。最后,对液体变焦镜头的发展前景和研究方向进行了展望和总结。
Compared with the traditional mechanical zoom lens,the variable-focus liquid lens has a smaller lens,faster response time,lower cost and higher integration capabilities.These lenses are widely used in image acquisition,target tracking and feature recognition.The performance and applications of liquid lenses are determined by the focal length adjustment method.This paper summarizes the progress of liquid crystals,dielectrophoresis,electrochemistry,electrowetting principle-based function control variable-focus lenses,electrostatic force,electromagnetic force,pressure regulation,and environmental-response-technology-based mechanical driven variable-focus lenses.The integrated applications of variable-focus liquid lenses in optofluidic chips are introduced.Also,the major obstacles and the settlement are described.Furthermore,the development potential and future research direction of the variable-focus liquid lens are also predicted and summarized.
