液晶 (LC) 单元可与光纤结合使用来开发廉价且高效的传感器，例如电压传感器或水听器。在本文中，我们应用有效的张量模型来描述镀金变形螺旋铁电液晶（DHFLC）单元的反射。我们表明，根据入射光的偏振，可以获得对施加到电池的电压的线性电光响应。将理论结果与实验结果进行比较，得出准确的一致性。
Liquid crystal (LC) cells can be used in conjunction with optical fibres to develop cheap and efficient sensors, such as voltage sensors or hydrophones. In this paper we apply an effective tensor model to describe reflection from gold-coated deformed-helix ferroelectric liquid crystal (DHFLC) cells. We show that, depending on the polarisation of the incident light, it is possible to obtain a linear electro-optical response to the voltage applied to the cell. Theoretical results are compared with experimental results yielding accurate agreement.
