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.
