在这封信中，展示了在宽范围内具有可调焦距的自适应透镜。通过改变射流透镜的形状来实现焦距调节，而不需要任何机械运动部件。在这种装置中展示的最短焦距为41 mm，这对应于0.24的大数值孔径和2.05的小F数。在该流体自适应透镜中，使用正标准测量的最高分辨率为25.39 lp/mm。
Fluidic adaptive lenses with an adjustable focal length over a wide range were demonstrated in this letter. The focal length adjustment was achieved by changing the shape of the fluidic lens without any mechanical moving parts. The shortest focal length demonstrated in such devices is 41 mm, which corresponds to a large numerical aperture of 0.24 and a small F number of 2.05. The highest resolution measured using a positive standard is 25.39 lp/mm in this fluidic adaptive lens.
