Feasibility study of birefringent electro-optic NIR FTS imaging systems

摘要

Fourier-transform imaging systems can rapidly provide a great deal of information in a scene. Many applications require systems with no moving parts. One proposed approach uses birefringent crystal stages interspersed with liquid crystal cells acting as achromatic polarization rotators. Previous research has revealed that this system may have limited applicability because of severe limitations of the field-of-view for systems with large OPD. We provide a more in-depth analysis of these limitations using mostly Extended Jones Matrix simulations. We also propose a design modifications which greatly improves FOV, allowing higher resolutions to be achieved.
