Assessment of multi-spectral weapon systems requires generation of multi-spectral scenes. These scenes are generated by different sources which are then combined. Beam combination of scenes with a field of view of few degrees involves large and costly beam combiners, moreover, available materials for beam combiners are limited in their spectral range. Phase I of this project provides conceptual design and laboratory demonstration of signal combination technique which will operate from the UV to the far IR spectrum, allowing for a true multi-spectral scene to be generated. This technique will yield a cost effective beam combination for projectors with fields of view larger than the field of view of the units under test.Anticipated benefits/potential applications:This project will enable wide field of view and multi-spectral scene generations in an economical method, with large flexibility in beam combination ratio and insensitivity to angle of incidence.
