This technology comprises a device geometry, based on the flexoelectric-optic effect in a chiral nematic liquid crystal, which is capable of linear multi-level phase modulation and frame rates in excess of several kHz. The multi-level phase modulation from these devices has potential for application in holographic projectors, optical correlators and adaptive optics.

By employing flexoelectric devices one can now modulatethe phase of light at frame rates well above those detected by the eye, thereby enabling improvement of image quality in holographic projectors as well as the implementation of real-time adaptive opthalmic imaging for high resolution diagnosis of retinal disease.
