چکیده

A comprehensive analysis of fundamental factors and their effects on the performance of liquid crystal (LC)-based lenses is given. The analysis adopts numerical LC director and electric field simulation, as well as scalar diffraction theory for calculating the lens performance considering different variable factors. A high-efficiency LC lens with concentric electrode rings is fabricated for verifying and enriching the analysis. The measurement results are in close agreement with the analysis, and a summary of key factors is given with their quantitative contributions to the efficiency.

Near-diffraction-limited and low-haze electro-optical tunable liquid crystal lens with floating electrodes.

A near-diffraction-limited, low-haze and tunable liquid crystal (LC) lens is presented. Building on an understanding of the key factors that have limited the performance of lenses based on liquid crystals, we show a simple design whose optical quality is similar to a high quality glass lens. It uses 'floating' electrodes to provide a smooth, controllable applied potential profile across the ape...

Tunable electronic lens using a gradient polymer network liquid crystal

Tunable electronic lenses using gradient polymer network liquid crystal ~PNLC! cells were demonstrated. By changing the photomask pattern, both positive and negative lenses were fabricated. The advantages of such a PNLC lens are low operation voltage, large aperture size, and simple electrode design. To overcome the polarization dependence, stacking two orthogonal homogeneous PNLC cells is cons...

Adaptive dielectric liquid lens.

A tunable-focus liquid lens using dielectrophoretic effect is demonstrated. When a voltage is applied to a dielectric liquid droplet, the generated electric field inside the droplet is inhomogeneous. As a result, the liquid bears a dielectric force and its surface profile can be reshaped which causes the focal length to change. Adaptive lenses with different apertures are fabricated and their p...

Tunable - Focus Liquid Crystal Lens

Since liquid crystal (LC) was proposed for making a tunable lens, the LC based zoom lens has been studied extensively for machine vision, photonics, information processing and eye glasses. Various approaches for making LC tunable lenses exists. Among them three methods are presented in this seminar: flat LC spherical lenses, microlenses made of nanosized polymer dispersed LC and Fresnel type sw...
