Enhanced night vision goggle assembly

1. Technical Field. A system (S) for combining multi-spectral images of a scene includes a channel () for transmitting a scene image () in a first spectral band. A separate, second detector () senses the scene in a second spectral band. The second detector () has an image output that is representative of the scene. A display () displays an image () in the second spectral band. A beam mixer () combines the image output () in the first spectral band with the displayed image (), and conveys the combined multi-spectral images to an output () for a user (U).
