【摘要】 本文介绍一种新型光控系统，系统中应用ＰＬＺＴ陶瓷片作为光执行器件实现光机转换，将两片极化后的ＰＬＺＴ陶瓷片按极化方向相反粘贴，形成双压电晶体型光执行器件，根据光信号来控制ＰＬＺＴ陶瓷双晶片的机械变形，实现光控伺服系统更多还原

【Abstract】 This paper introduced one new photostrictive actuator PLZT of photoservosystem.We adopted the bimorph structure to get large displacement, which adhered two identical PLZT elements so as to reverse their polarizing directions, so optical signals can control the expand and contract of PLZT bimorph structure in photoservosystem.更多还原
