| 摘 要： | 为了在较大视场范围内获得干涉直条纹以提高干涉数据的提取精度,设计了一种基于组合Savart板的宽场偏振干涉成像光谱仪.组合Savart板由正负晶体制作的两个Savart板组合而成.文中推出了组合Savart板的光程差和横向剪切量与入射角的理论表达式,并给出了具体设计实例.计算机模拟分析结果表明,在光谱分辨率和晶体总厚度相同的前提下,组合式Savart板获得干涉直条纹的视场是传统Savart偏光镜视场的10倍.

| Abstract: | To obtain straight interference fringes over larger field of view and thus acquire high-accuracy interference data, a wide field of view polarization interference imaging spectrometer based on a combined Savart plate is presented. The Savart plate is composed of positive and negative uniaxial crystals. The relationship between the optical path difference and incident angle is given. By numerical modeling and analysis examples with similar spectral resolution and total thickness, The simulation results show that the field of view to obtain straight interference fringes for the combined Savat plate is ten times as large as that for the conventional Savart plate. |
