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

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 …

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

Optical devices like virtual reality (VR) headsets present challenges in terms of vergence-
accommodation conflict that leads to visual fatigue for the user over time. Lenses available …

In this paper, we demonstrate a holographic polymer-stabilized blue-phase liquid crystal
grating fabricated using a visible laser. As blue phase is stabilized by the interfered light …

The resultant oleic acid (OA)-modified LaF3 (OA-LaF3) NPs were easily dispersed well in
common organic solvents or liquid crystals (LCs). Usually, the stability of BPs depends on a …

In this paper, we use a dynamic mask lithography system to fabricate a polymer-stabilized
blue-phase Fresnel lens. Fresnel-zone patterned light is directly generated by a …

The authors report an optical switchable lens using an electrowetting liquid lens. The optical
switchable lens is obtained through two different paths, either the annular aperture or the …

ABSTRACT A simple method for fabricating a polarisation independent blue-phase liquid
crystal Fresnel lens (BPLCFL) is demonstrated by utilising the photo-polymerisation-induced …

Редкоземельные элементы обладают уникальными электронными свойствами, что
делает наноматериалы на их основе крайне перспективными в области …
