An electrically tunable-focusing liquid crystal lens with a low voltage and simple electrodes.
An electrically tunable focusing LC lens with a low voltage and simple planar electrodes is demonstrated. The inhomogeneous electric field of the LC lens without any hole-patterned-electrode is generated by using an embedded polymeric layer with a gradient distribution of dielectric constants (or relative permittivity). LC directors in the LC layer experience spatially inhomogeneous voltages ev...
متن کاملA Novel High-Sensitivity, Low-Power, Liquid Crystal Temperature Sensor
A novel temperature sensor based on nematic liquid crystal permittivity as a sensing magnitude, is presented. This sensor consists of a specific micrometric structure that gives considerable advantages from other previous related liquid crystal (LC) sensors. The analytical study reveals that permittivity change with temperature is introduced in a hyperbolic cosine function, increasing the sensi...
متن کاملLiquid crystal lens focusing in monocentric multiscale imagers
In multiscale imagers a single objective lens is shared by multiple secondary optical systems, so that a high-resolution wide-angle image is acquired in overlapping fields sensed by multiple conventional focal planes. In the “AWARE2” 2 Gigapixel imager, F/2.4 optics cover a 120 degree field of view using a monocentric glass primary lens shared by 221 molded plastic subimagers, each with a 14 Me...
متن کاملNovel Adaptive Liquid Lens Actuated by Liquid Crystal Pistons
We demonstrate a novel adaptive liquid lens actuated by liquid crystal (LC) pistons. The dielectrophoretic force generated by the embedded in-plane-switching electrode causes the reciprocating movement of LC droplets which, in turn, changes the optical power of the resultant liquid lens. Such a microlens array is promising for 3D image processing. Author
متن کاملA new low-voltage-driven GRIN liquid crystal lens with multiple ring electrodes in unequal widths.
This work is dedicated to design a novel liquid crystal (LC) lens device with multiple ring electrodes in unequal widths, in order to offer tunability on focusing quality and to lower the level of applied voltage. The number and widths of the multiple ring electrodes are pre-designed and optimized to offer the on-line tunability on individual electrode voltages to render a better refraction ind...
