摘要： Inhomogeneous concentrated polymer network with approximately 90° twisted nematic liquid crystal (TN-LC) is used for fabricating lens and prisms. For forming a positive lens, the approximately 90° TN-LC polymer network concentration can gradually decrease from the center to the side edges. For forming a negative lens, the approximately 90° TN-LC polymer network concentration can gradually increase from the center to the side edges. The lens can be created by ultra violet (UV) light exposure to patterned photo masks. The lens can be tuned by applying voltage above the threshold voltage to the polymer network. The inhomogeneous 90° TN-LC polymer network can also be used in Fresnel lens and prisms. Applications of the invention can be used for micro lens, array, optical communication, micro-optics, adaptive optics and beam steering.
摘要翻译：使用具有约90°扭曲向列型液晶（TN-LC）的不均匀浓缩聚合物网络用于制造透镜和棱镜。为了形成正透镜，大约90°TN-LC聚合物网络浓度可以从中心到边缘逐渐减小。为了形成负透镜，大约90°TN-LC聚合物网络浓度可以从中心向侧边逐渐增加。透镜可以通过紫外（UV）光照曝光到图案化的照相掩模上。可以通过将高于阈值电压的电压施加到聚合物网络来调整透镜。不均匀的90°TN-LC聚合物网络也可用于菲涅尔透镜和棱镜。本发明的应用可用于微透镜，阵列，光通信，微光学，自适应光学和光束转向。

摘要： A liquid-filled variable focus lens cell is disclosed. The liquid lens cell consists of four parts: a clear distensible membrane, a transparent wall member, liquid with a fixed volume stored in lens cell chamber, and an annular periphery sealing ring. The inner surfaces of the annular sealing ring are sealed with distensible membrane. The radius of the annular sealing ring is changeable, similar to a conventional iris diaphragm. By tuning the radius of the annular sealing ring, the stored liquid in the lens cell will be redistributed, thus change the curvature of the distensible membrane. Therefore, the liquid lens cell can cause light to converge or diverge. The liquid filled lens can be operated mechanically or automatically.

摘要： An adaptive optical lens device, system and method of using the same is composed of at least two planar substrates and at least one homogeneous nematic liquid crystal (LC) layer. One planar substrate has a spherical or annular ring-shaped Fresnel grooved transparent electrode within it, the other has a transparent electrode coated on its inner surface. The thickness of the LC layer is uniform. When a voltage is applied across the LC layer, a centro-symmetrical gradient distribution of refractive index within LC layer will occur. Therefore, the LC layer causes light to focus. By controlling the applied voltage, the focal length of the lens is continuously tunable.

摘要： A variable focus liquid lens is formed using two substrates with at least two through holes in at least one of the substrates. One end of each through hole is covered with a distensible membrane, one on the exterior surface of the substrate and the other on the interior surface. The substrates are sealed about the periphery to form a chamber and the chamber is filled with a liquid material. When pressure is applied to the membrane the liquid in the chamber is redistributed to form the lens. The variable focus liquid-filled lens is formed by providing a first and second substrate, forming at least two through holes in at least one of the first and second substrate, sealing one end of each of the at least two holes with a flexible transparent membrane, and sandwiching a liquid in a chamber formed between the first and second substrate.
