1. A multiband camera system, said system comprising: a first sensor for generating a first object image and a first alignment image in a first frequency band; a second sensor for generating a second object image and a second alignment image in a second frequency band; an internal alignment assembly; and a splitter for directing radiation in said first frequency band from said object to said first sensor to form said first object image, directing radiation in said second frequency band from said object to said second sensor to form said second object image, directing radiation in said first frequency band from said internal alignment assembly to said first sensor to form said first alignment image, and directing radiation in said second frequency band from said internal alignment assembly to said second sensor to form said second alignment image wherein said first alignment image and said second alignment image establish a reference for aligning the first and second object images.
