Abstract
A novel optical control system using nematic liquid crystals and acoustooptic devices is introduced that can provide compact, lightweight, low cost, transmit/receive mode, high performance (greater than 8 bits), truly analog, amplitude and phase control for large phased array antennas. The system provides independent amplitude and phase calibration and control capabilities across the array.
