ABSTRACT:
A space modulation matrix is composed of semiconductor transmittivity modulation elements arranged in a matrix pattern. A transmittivity of the transmittivity modulation elements is changed by supplying a light or applying a voltage greater than a switching voltage of the transmittivity modulation elements to a selected number of the transmittivity modulation elements, so that a space modulation is provided on the space modulation matrix, and is renewed by any number of times.
