Abstract

We report on complete wave-front control with amplitude- and phase-modulation liquid-crystal devices (LCD’s). A twisted nematic device is used for amplitude modulation, and an electrically controlled birefringent device is used for phase modulation. Because the LCD’s are optically coupled with afocal optics and are driven by individual LCD driver circuits, the amplitude and the phase can be controlled two dimensionally and independently. Complex amplitude data are calculated, and on-axis computer-generated holograms are directly recorded. Furthermore, we discuss LCD performance requirements for high-quality reconstruction.
