Abstract

PURPOSE:To obtain a space lattice whose lattice interval can be varied electrically, by applying positive voltage by selecting some of plural electrodes arrayed on a substrate consisting of a material having electric and optical effects, also negative voltage by selecting some of other electrodes, and controlling a degree of transmission of light. CONSTITUTION:On a platelike substrate (for instance, a PLZT substrate) 1 having electric and optical effects, plural electrodes 11, 12,- are arrayed at a constant pitch. On both sides of this substrate 1, polarization plates 3, 4 are placed so that the planes of polarization are at right angles to each other. When voltage of positive or negative is selectively applied to each electrode 11, 12,- by a driving circuit 5 and an incident luminous flux is provided, it is possible to obtain a space lattice whose lattice interval of bright and dark periods is selectively varied.
