摘要

In this Letter,a Gabor superlens with variable focus is presented.This configuration uses tunable liquid lenses in the third microlens array of the Gabor superlens.By applying voltage,the radius of curvature of the micro-tunable doublet arrays changes,and the Gabor conditions are fulfilled at different focal planes.As a consequence,the magnification of the image at the focal planes changes,and a zoom effect is observed.The marginal depth plane for this system goes from 0.86 to 0.89 mm.The optical simulation,calculations,and results of the simulated optical system performance are presented.
