Abstract: A spatially non-uniform electrode structure is proposed for controlling a spatially non-uniform electric field driving a tunable liquid crystal lens. The spatially non-uniform electrode structure enables the generation of a predetermined spatially non-uniform electric field profile where complex capacitive coupling between multiple different electrically floating neighboring electrode segments is employed for the generation of the electrical field of desired form by supplying an initial electric potential to a limited number of electrodes.

Abstract: Variable liquid crystal devices for controlling the propagation of light through a liquid crystal layer use a frequency dependent material to dynamically reconfigure effective electrode structures in the device. The frequency of a drive signal that generates an electric field in the device can be varied, and the frequency dependent material has different charge mobilities for the different frequencies. At a low charge mobility, the frequency dependent material has little effect on the existing electrode structures. However, at a high charge mobility, the frequency dependent material appears as an extension of the fixed electrodes, and can be used to change the effective electrode structure and, thereby, the spatial profile of the electric field. This, in turn, changes the optical properties of the liquid crystal, thus allowing the optical device to be frequency controllable.

Abstract: An electrically controllable optical lens apparatus makes use of fixed lenses and an active optical element together in a lens enclosure. The enclosure may be a barrel structure that is easily mounted to a camera device having an image sensor. The active optical element, such as a tunable liquid crystal lens, receives an electrical signal from the camera device via electrical conductors integral with the lens enclosure that provide electrical pathways between the active element on the interior of the enclosure and surface contacts on the camera device. The enclosure may be a two-piece structure, and the electrical conductors may be attached to either piece of the structure. The lens enclosure may also be threaded for attachment to the camera device. The electrical conductors may also use spring loaded contact portions or molded interconnect devices.

Abstract: A wafer level method of manufacturing a liquid crystal optical device removes the need for a rigid barrier fillet while minimizing any risk of contamination of the liquid crystal. An uncured adhesive may be deposited on a bottom substrate and partially cured to form a liquid crystal barrier. After addition of the liquid crystal and a top substrate, the adhesive is fully cured to bond the substrate layers together. An uncured adhesive may be used together with the partially cured adhesive, and may be deposited separately or filled into an extracellular matrix surrounding a plurality of liquid crystal cells. The adhesive may be cured by a variety of means, including light that may be spatially modulated. One or both of the substrates may be deformed during assembly so as to create a structure with a lensing effect on light passing through the liquid crystal region.
