摘要
The electrical adjustment of the optical performance of liquid crystal cylindrical micro-lens array of 128x128, which is based on the field controlling effect of liquid crystal dielectric behaviour, is realised through constructing smart liquid crystal electro-optic structure, and orderly modulating the refractive index of liquid crystal material and its spatial distribution. According to the elastic continuum theory of liquid crystal, it is firstly described on the formation of specific refractive index spatial distribution of liquid crystal molecules, which is driven by applied electric-field. Furthermore, the white-light focusing, the far-field white-light interference and the monochromatic laser interference are all measured extensively and discussed in details.
