Multi-segment liquid crystal spatial light modulators have received much attention recently for use as high-precision wave-front control devices for use in astronomical and non- astronomical applications. They act much like piston only segmented deformable mirrors. In this paper we investigate the use of these devices in conjunction with a Shack- Hartmann wavefront sensor. In this paper we consider a zonal algorithm in order to take advantage of high speed matrix multiply hardware which we have in hand.
