Liquid crystal lens has the characteristic of variable focal length. Many studies have demonstrated that electronically controlled focusing without mechanical movements can be realized by using liquid crystal lenses in imaging system. In this paper, a four-electrodes liquid crystal lens with a rectangular aperture is applied to focus. The aperture’s aspect ratio of the liquid crystal lens can be designed arbitrarily so that installing it with the periscope lens in phones becomes possible.

“…Liquid crystals are a material of choice in many optical devices [1]: displays [2], optical light modulators [3], liquid crystal light valves [4], diffractive waveplates [5] and diffraction elements [6], waveguides [7] soliton channels [8] and lenses [9], to name a few. In all these devices it is essential that the geometry of the cell and its liquid crystal-related properties, e.g.…”

We track the non-uniformity of a wide area liquid crystal device using multiple cross-polarized intensity measurements. They give us not only accurate estimates of the core physical liquid crystal parameters, such as elastic constants, but also spatial maps of the device properties, including the liquid crystal thickness and pretilt angle. A bootstrapping statistical analysis, coupled with the multiple measurements, gives us reliable error bars on all the measured parameters.
