Abstract
Spatial and temporal characteristics of a 128 x 128 zero-twist nematic liquid-crystal spatial light modulator are investigated for wave-fron t generation at a wavelength of 632.8 nm. The modulator is found to ha ve the capability of producing at least eight phase levels between 0 a nd 2 pi, and the rate of arbitrary phase modulation is limited to appr oximately 4.5 Hz. Wave-front generation of the first 55 Zernike polyno mials is demonstrated. (C) 1998 Optical Society of America.
