Optical element and display board

Abstract

PURPOSE:To obtain a new optical element by composing the optical element of a stimulation transmitting mechanism which stimulates polymer gel, fixing at least part of the polymer gel, and utilizing the flexibility of the polymer gel. CONSTITUTION:The red-shaped polymer gel 3 where an optical path 2 is united is fixed by support bases 4 in an optical cell 1 whose front surface is transparent, two electrodes 5 and 5' are arranged in the parallel direction of the polymer gel 3, and the cell 1 is filled with an electrolytic solution 6. The electrodes 5 and 5' are connected through DC power sources 7 and 7' and switches 8 and 8'. The switches 8 and 8' are both OFF, so the polymer gel 3 is straight and the light of a light source 9 behind the optical path is observed on the front surface of the optical cell. Then when the switch 8 is turned ON, the polymer gel deflects toward a negative polarity and the light of the light source 9 is not observed. Further, the switch 8 is turned OFF and the switch 8' is turned ON, so that the light of the light source 9 is observed. The two states reversibly change and the function of an optical element is obtained by this principle.
