An approach is presented that allows an electrically variable liquid crystal lens to operate as a spherical lens, then be switched into a variable prism, axicon, etc. This is achieved by a simple phase optimization algorithm enabled by the presence o

An electrically variable liquid crystal lens is used to compensate the aberrations of commercial gradient index rod lenses used for deep brain endoscopy. This is achieved by the use of a weakly conductive layer in the so-called “modal control” le

Liquid crystalline (LC) materials are user friendly materials for electro optics applications [1], the most popular of which is the flat panel display [2]. Another interesting development, involving LCs, was the electrically variable lens that alread

We propose a simple technique allowing the correction of the inherent wavefront asymmetry in electrically variable liquid crystal lenses with relatively small diameters. This is achieved by splitting the peripheral hole patterned electrode of the len
