Presents readers with the basic science, technology, and applications for every type of
adaptive lens An adaptive lens is a lens whose shape has been changed to a different focal …

With rapidly expanding interest in liquid crystalline polymers and elastomers among the
liquid crystal community, researchers are currently exploring the wide range of possible …

Despite the recent advances in augmented reality (AR), which has shown the potential to
significantly impact on our daily lives by offering a new way to manipulate and interact with …

Liquid crystal polarization gratings exhibit high diffraction efficiency (~ 100%) in thin material
layers comparable to the radiation wavelength. We demonstrate that they can be combined …

In this Letter, we disclose a fast switchable Fresnel zone lens (FZL) by confining the
ferroelectric liquid crystals (FLCs) in multiple microscopically defined photo-aligned …

We demonstrated a highly efficient, polarization-independent and electrically tunable
Fresnel lens based on dye-doped liquid crystal using double-side photoalignment …

We demonstrate a liquid crystal (LC)-based square lens array with two focusing modes
according to the polarization state of the input light. The homogeneously aligned LC layer is …

Publisher Summary Adaptive or varifocal lenses with variable focusing powers have
attracted much attention because of their wide applications in vision care, consumer …

Polymer films nanoimprinted with checkerboard patterns of square wells align calamitic
(rodlike) liquid crystals vertically, horizontally, or tilted depending on the depth/width ratio of …

This work demonstrates a reflective Fresnel zone plate based on dye-doped cholesteric
liquid crystals (DDCLC) using the photo-induced realignment technique. Illumination of a …
