Interferometric image processing systems based on image inversion normally use multiple paths with inversion mirrors. Since such systems must meet strict requirements of alignment and stability, a common-path implementation using polarization channels and six anisotropic optical elements was recently introduced. We demonstrate here the operation of a common-path polarization-based image-inversion interferometeric system using only two anisotropic lenses. Applications such as spatial parity analysis and image centroid measurements are examined theoretically and demonstrated experimentally.

用于干涉信息处理的双透镜各向异性图像反演系统

基于图像反转的干涉式图像处理系统通常使用带有反转镜的多条路径。由于此类系统必须满足严格的对准和稳定性要求，因此最近引入了使用偏振通道和六个各向异性光学元件的共通路径实现。我们在这里演示仅使用两个各向异性透镜的基于共路径偏振的图像反转干涉仪系统的操作。从理论上检查并通过实验证明了诸如空间奇偶分析和图像质心测量之类的应用程序。
