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 crystals (LCs) technology have a well‐established history of applications in visible
light, particularly in the display industry. However, with the rapid growth in communication …

We report a noninvasive strategy for electrically stimulating neurons at depth. By delivering
to the brain multiple electric fields at frequencies too high to recruit neural firing, but which …

Developing head-mounted displays (HMDs) that offer uncompromised optical pathways to
both digital and physical worlds without encumbrance and discomfort confronts many grand …

Purpose To outline the refractive problems associated with presbyopia and to review the
basis and relative merits of currently‐available methods for their correction, with detailed …

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 …

We demonstrate the implementation of a compact tunable-focus liquid lens suitable for
adaptive eyeglass application. The lens has an aperture diameter of 32 mm, optical power …

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 …

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 …

Natural compound eyes provide the inspiration for developing artificial optical devices that
feature a large field of view (FOV). However, the imaging ability of artificial compound eyes …
