title: Characteristics of a 128 x 128 liquid-crystal spatial light modulator for wave-front generation.
abstract: 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 4.5 Hz. Wave-front generation of the first 55 Zernike polynomials is demonstrated.
