Variable-focus liquid lens for miniature cameras
The meniscus between two immiscible liquids can be used as an optical lens. A change in curvature of this meniscus by electrowetting leads to a change in focal distance. It is demonstrated that two liquids in a tube form a self-centered lens with a high optical quality. The motion of the lens during a focusing action was studied by observation through the transparent tube wall. Finally, a minia...
متن کاملTunable - Focus Liquid Crystal Lens
Since liquid crystal (LC) was proposed for making a tunable lens, the LC based zoom lens has been studied extensively for machine vision, photonics, information processing and eye glasses. Various approaches for making LC tunable lenses exists. Among them three methods are presented in this seminar: flat LC spherical lenses, microlenses made of nanosized polymer dispersed LC and Fresnel type sw...
متن کاملSurface localized polymer aligned liquid crystal lens.
The surface localized polymer alignment (SLPA) method allows complete control of the polar pretilt angle as a function of position in liquid crystal devices. In this work, a liquid crystal (LC) cylindrical lens is fabricated by the SLPA method. The focal length of the LC lens is set by the polymerization conditions, and can be varied by a non-segmented electrode. The LC lens does not require a ...
متن کاملTwisted-nematic liquid-crystal pixelated active lens
Liquid-crystal active lenses are classical imaging systems in which a liquid-crystal spatial light modulator is placed in a pupil plane. The modulator controls the phase of the optical wave in the pupil and achieves an arbitrary wavefront shape, that is limited only by the available modulation depth and resolution. The possibility of using a twisted-nematic liquid-crystal television in the pupi...
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
