摘　　要：介绍了基于液晶取向改变的检测方法的机理,并对其应用进行综述,并指出经过进一步研究有望将其开发成一种全新的、用日光等自然光做光源、目视检测、无需电源、可在国防、环保、食品、医药、公共安全和生命科学等领域中进行高灵敏度、高分辨率、现场快速检测的微型传感器。The detecting principle based on the orientational transition of liquid crystal was introduced and the applications were reviewed in this paper. The method may provide the basis of a new passive detector using daylight as the light source and detected using naked eyes. The passive detector will be suitable for application to a wide range of areas including national defence, food, drug, public security, life science and so on.
