摘要： An optical apparatus comprises an optical device having an optically functional material sandwiched between a pair of substrates with electrodes formed on opposing surfaces. The optically functional material has such a characteristic that intensity of light issuing from the optical device changes asymmetrically in response to inversion of the polarity of an applied external field. Pulse voltages of one polarity for determining the intensity of the issuing light and pulse voltages of an opposite polarity are applied from a source at a predetermined period so that an average voltage is zeroed within the predetermied period. The issuing light intensity under the application of the pulse voltages of one polarity and the issuing light intensity under the application of the other pulse voltages are selected or changed by a switching unit.
