Abstract

Additional electrical impedance is introduced in a liquid crystal lens by adding a floating (nonconnected) electrode. This enables excellent optical quality in a very simple operation mode (frequency tuning of the lens’ optical power at a fixed driving voltage). The comparative analysis of this lens confirms its suitability for mobile imaging applications.
