液晶位相调制器在非显示领域有广泛的应用,例如自适应光学中的波前校正、大气湍流模拟、光学相控阵的光束指向等.在这些应用中液晶的响应速度、位相调制范围、色散等特性非常关键.围绕对这些特性的改进,本文总结了近年来人们在液晶器件设计、驱动方法改进以及液晶色散研究方面的理论计算方法,这为人们在提高液晶器件电光响应特性、预期其性能等方面的需求,提供了非常有价值的参考.
Recently, liquid crystal (LC) with its promising electro-optical characteristics arouses the interest in many non-display applications, such as the wavefront corrector in adaptive optics, atmospheric turbulence simulator, and optical steering as a optical phased array.In these applications, the key LC parameters include its response time, phase stroke and dispersion.In the paper, we focus on these key parameters and report the advancement of theoretical calculation algorithms in LC optimal parameters design, driving improvement and LC dispersion description.And these are valuable and helpful to improve the LC device design and estimate their electro-optical properties.
