利用光自聚焦和Ｆ－Ｐ腔两种手段，对ＥＢＢＡ液晶进行了光学双稳态研究。实验是在６０μｍ液晶薄膜中采用连续Ａｒ＋激光器进行，确定出温度与光学双稳态和多级光学双稳态回线的关系，讨论了ＥＢＢＡ液晶在固态相和液晶相及其相变过程中光学双稳态的机制。
The optical bistability of EBBA liquid crystal was studied by means of light self-focusing and F-P cavity. The experiment was carried out in a 60μm liquid crystal thin film by using a continuous Ar + laser to determine the relationship between temperature and optical bistable and multi-stage optical bistable return lines. In the process of solid phase, liquid crystal phase and phase transition of EBBA, Bistable mechanism.
