Liquid crystal lenses have promise in optical systems owing to their tunability combined with low electrical power, cost, and weight. A good example of such a system is switchable contact lenses for the correction of age‐related presbyopia. Sufficiently large phase modulation can be done using nematic liquid crystals in a meniscus lens configuration. However, the birefringent materials are inherently polarisation dependent, usually requiring orthogonal polarisations to be focussed separately. A novel method is presented for producing polarisation independent lenses based on reactive mesogens. Results are presented for a 2‐level and 3‐level diffractive Fresnel lenses, and the promise of the technique for use in refractive lenses such as contact lenses is discussed.

使用压纹反应性液晶元的偏振无关液晶透镜和隐形眼镜

由于液晶透镜的可调性以及低电功率，成本和重量，它们在光学系统中很有前途。这种系统的一个很好的例子是可开关式隐形眼镜，用于矫正与年龄有关的老花眼。使用弯月形透镜配置中的向列液晶可以完成足够大的相位调制。但是，双折射材料本质上是偏振相关的，通常需要正交偏振分别聚焦。提出了一种基于反应性液晶元生产偏振无关透镜的新方法。给出了2级和3级衍射菲涅耳透镜的结果，并讨论了用于隐形眼镜等折射透镜的技术前景。
