title: Imaging with complex ray-optical refractive-index interfaces between complex object and image distances.
abstract: Building on recent work on windows that can be modeled as interfaces between materials with a complex ray-optical refractive-index ratio, we define here objects and images at complex positions. We give an example of an optical component that performs imaging between real and complex object and image positions.
