    摘要： A liquid crystal device for controlling scattering of light beams incident upon a liquid crystal layer so as to modulate the light beams includes: a first lens array having lenses corresponding to the liquid crystal layer, the lenses causing the light beams transmitted from the liquid crystal layer, the lenses causing the light beams transmitted from the liquid crystal layer to travel toward a focal plane; a mask for shielding scattered light transmitted from the first lens array as well as allowing non-scattered light to pass through, the mask having a plurality of aperture portions which are formed along the focal plane to correspond to the lenses of the first lens array so as to allow non-scattered light transmitted from corresponding lenses to pass through; and a second lens array having lenses arranged to correspond to the aperture portions of the mask, the lenses substantially collimating the non-scattered light transmitted from corresponding aperture portions of the mask.

    摘要： A nonlinear optical material comprises a solid solution of an organic guest compound having an electron donative group or an electron attractive group. The organic guest compound is contained in the nonlinear optical material preferably an oriented form through orientation under melting by application of a DC electric field. The guest compound is preferably a para-di-substituted benzene derivative represented by the formula: ##STR1## wherein A is an electron donative group and B is an electron attractive group.
