Spatial and temporal characteristics of a 128x128 zero-twist nematic liquid-crystal spatial light modulator are investigated for wave-front generation at a wavelength of 632.8 nm. The modulator is found to have the capability of producing at least eight phase levels between 0 and 2pi , and the rate of arbitrary phase modulation is limited to approximately(More)
