Patent number: 10747084Abstract: A liquid crystal optical device is described configured to provide variable beam steering or refractive Fresnel lens control over light passing through an aperture of the device. The device includes at least one layer of liquid crystal material contained by substrates having alignment layers. An arrangement of electrodes is configured to provide a spatially varying electric field distribution within a number of zones within the liquid crystal layer. The liquid crystal optical device is structured to provide a spatial variation in optical phase delay with a transition at a boundary between zones which is an approximation of a sawtooth waveform across the boundaries of multiple zones. The arrangement of electrodes, device layered geometry and methods of driving the electrodes increase the effective aperture of the overall optical device.Type: GrantFiled: June 14, 2019Date of Patent: August 18, 2020Assignee: LENSVECTOR INC.Inventors: Tigran Galstian, Karen Asatryan, Armen Zohrabyan, Marco Thiboutot, Vladimir Presniakov

Patent number: 9910246Abstract: An auto-focus system employing a tunable liquid crystal lens is provided that collects images at different optical power values as the liquid crystal molecules are excited between a ground state and a maximum optical power state tracking image focus scores. An image is acquired at a desired optical power value less than maximum optical power established with the liquid crystal molecules closer a fully excited state than the maximum optical power state having the same image focus score. This drive signal employed during image acquisition uses more power than was used to achieve the same optical power value during the auto-focus scan, while actively driving the liquid crystal molecules is fast. A pause due to image transfer/processing delays after acquisition is employed to allow slow relaxation of the liquid crystal molecules back to the ground state in preparation for a subsequent focus search.Type: GrantFiled: June 29, 2016Date of Patent: March 6, 2018Assignee: LENSVECTOR INC.Inventors: Armen Zohrabyan, Tigran Galstian, Karen Asatryan, Vladimir Presniakov, Marco Thiboutot, Aram Bagramyan, Amir Tork, Jeffrey James Parker, Ted Cooper, Behzad Khodadad, Gongjian Hu, Chong I Cheang
