摘要：
n electro-optical light shutter (3) includes a ceramic body (6) exhibiting electro-optical effect and a pair of electrodes (4, 5) for applying A.C. voltage to the ceramic body (6) to control the electro-optical effect. The ceramic body (6) is formed of PLZT ceramic having a memory effect at room temperature and which loses the memory effect at an elevated operating temperature caused by application of A.C. voltage to the ceramic body (6). Additionally, a heater (51) may be used to raise the operating temperature of the ceramic body (6).
