Presbyopia is a global problem affecting over a billion people worldwide. The prevalence of
unmanaged presbyopia is as high as 50% of those over 50 years of age in developing world …

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 …

Liquid Crystal Devices are crucial and ubiquitous components of an ever-increasing number
of technologies. They are used in everything from cellular phones, eBook readers, GPS …

We demonstrate polarizer-free and fast response microlens arrays based on optical phase
modulation of polymer-stabilized blue phase liquid crystal (PSBP-LC). Polarization …

Electrically tunable focusing liquid crystal (LC) lenses are reviewed in this paper. The
distribution of the orientations of LC directors which is controlled by electric fields results in a …

With the distinct advantages of high resolution, small pixel size, and multi-level pure phase
modulation, liquid crystal on silicon (LCoS) devices afford precise and reconfigurable spatial …

An electrically tunable-focusing and polarizer-free liquid crystal (LC) lens for ophthalmic
applications is demonstrated. The optical mechanism of a LC lens used in human eye …

Presbyopia is an age-related disorder where the lens of the eye hardens so that focusing on
near objects becomes increasingly difficult. This complaint affects everyone over the age of …

Polarization-independent liquid-crystal (LC) phase modulators can significantly improve the
efficiency and reduce the complexity of optical systems. However, achieving good …

Electrically tunable liquid crystal microlenses have attracted strong research attention due to
their advantages of tunable focusing, voltage actuation, low power consumption, simple …
