Abstract

In order to solve the polarization-related problems of liquid crystal lenses and the leakage problems of liquid lenses, this paper proposes a fabrication method of high-performance varifocal microlens arrays based on integrated PDMS gels and parallel PZT driver. When the driving voltage of the PZT piezoelectric ceramic is changed, the surface profile of the PDMS gel in the PZT will change accordingly, resulting in the change of the focal length of the lens. Experiments show that the PDMS gel lens has good imaging quality, small distortion, and an approximately linear relationship the focal length of PDMS gel lens and the voltage applied to the PZT piezoelectric ceramic. The focal length changes from -60V to 60V is 12.6mm~219.5mm. This lens is compact, simple to make, low cost, and has good optical performance. It can be widely used in camera equipment, mobile phone cameras, tablets, drones, surveillance and other smart devices.
