Paper Abstract

The purpose of this study is to design and analyze a new asymmetrical liquid-filled lens. By controlling the tilt angle of the pressure ring and the hydraulic pressure of this lens, either the light direction or the focal length can be changed. For this study, the ANSYS workbench program is employed to analyze the membrane deformation of the lens under different liquid pressures and asymmetrical conditions. ZEMAX is used to compute its effective focal length. To demonstrate the feasibility of the asymmetrical lens, a prototype is developed and tested. The analysis and experimental results show good agreement.
