Liquid crystals are valuable materials for applications in beam steering devices, specifically in the field of adaptive optics. This paper provides an overview of the properties of liquid crystals that make them useful in this field, as well as a detailed discussion of specific liquid crystal devices that act as switchable optical components. The relative advantages and disadvantages of different devices and techniques are summarised.
Liquid crystals are valuable materials for applications in beam steering devices. In this paper, an overview of the use of liquid crystals in the field of adaptive optics specifically for beam steering and lensing devices is presented. The paper introduces the properties of liquid crystals that have made them useful in this field followed by a more detailed discussion of specific liquid crystal devices that act as switchable optical components of refractive and diffractive types. The relative advantages and disadvantages of the different devices and techniques are summarised.
