Abstract
The vast majority of liquid crystal (LC) devices are used today in displays and image projection systems. The goal of this work is to demonstrate that with LC other helpful optical components can also be built. Two classes of devices are presented. The first class represent 1-dimensional spatial light modulators with high resolution electrodes to be used as beam steering devices. These devices are parallel LC cells and represent electrically controllable birefringent phase gratings. The second class involves what we call polarization converter devices and which represent the passive LC devices. These nematic LC devices are fairly easy to fabricate and a new class of light fields can be generated with them, namely linearly polarized light with axial symmetry. These fields are very difficult to generate unless the LC components described here are used.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
