摘要
石英晶体波片的延迟量对入射倾角有很大的敏感性,利用波片的这一特性,从普通的Lyot型双折射滤光片的基本原理出发,设计了一种新的Loyt型双折射调谐滤光片。调谐的方法是使石英波片绕平行于光轴的轴向转动。理论和实验证明这一设计有较好的可调性,可调范围比较宽。比普通的加入λ/4波片和λ/2波片的Lyot型双折射调谐滤光片简化了结构、降低了成本。
Because of the retardation of wave-plate sensitive to the incident angle, a new kind of tunable Lyot filter is designed. The method of tuning is rotating the wave-plate by the axial direction parallel to the optical axis. It is proved that this kind of tunable Lyot filter has the properties of favorable tunability, wide tunable range and so on.
