光流体可变光圈在图像采集、目标追踪、生物识别和其他便携式电子设备中具有重要的应用潜力。与机械光圈相比,该光圈孔径是近乎完美的可调圆形,且光流体可变光圈具有易于加工、结构紧凑、驱动便捷和功耗低等优点,故已成为当今微纳光学研究领域的热点之一。综述国内外现有光流体可变光圈技术的发展现况,通过总结前人的研究方法,展望未来光流体可变光圈的发展方向。
Optical Fluid Variable Apertures have important potential applications in image acquisition, target tracking, biometrics and other portable electronic devices. Compared with the mechanical aperture, the aperture aperture is almost perfect adjustable circular, and the optical fluid variable aperture has the advantages of easy processing, compact structure, convenient driving and low power consumption, it has become the field of micro-nano optical research One of the hot spots. In this paper, the development of current iris iris technology in China and abroad is reviewed. By summarizing the research methods of predecessors, the development direction of iris iris in the future is forecasted.
