Abstract

The system and method for combining two optical assemblies into the same volume, particularly when the field of view of the two assemblies are different, so that the overall volume and size, weight and power (SWaP) for the system is reduced. This also allows both subsystems (e.g., narrow field of view (NFOV) and wide field of view (WFOV) to use a single aperture and the same external protective window, reducing overall cost for a system of co-located dissimilar optical systems in a single aperture.
