Lenses with tunable focal length play important roles in nature by helping species avoid
predators and capture prey. Many practical devices mimic lens concept for imaging, sensing …

Optical lenses with electrically controllable focal length are of growing interest, in order to
reduce the complexity, size, weight, response time and power consumption of conventional …

An adaptive-focus lens is a device that is capable of tuning its focal length by means of an
external stimulus. Numerous techniques for the demonstration of such devices have been …

This work presents the application of an experimental nematic liquid crystal (LC) mixture
(1929) in a large aperture lens. The LC material is composed of terphenyl and biphenyl …

With the help of augmented reality (AR) and virtual reality (VR) systems, users can receive
information and connect with each other via near-eye displays (NEDs). However, several …

An augmented reality (AR) system involving the electrically tunable location of a projected
image is implemented using a liquid-crystal (LC) lens. The projected image is either real or …

In this study we present an investigation of electrically tunable progressive lenses utilizing
liquid crystals (LC). We introduce a polarized progressive LC lens capable of dynamically …

Phase-only devices based on liquid crystals are becoming popular solutions for a high
number of applications in many diverse areas. The use of an electrooptic material such as …

Augmented reality (AR), which use computer-aided projected information to augment our
sense, has important impact on human life, especially for the elder people. However, there …

In this work, a technique to generate aspherical liquid crystal lenses with positive and
negative optical power is experimentally demonstrated. The main enabling element is a …
