Paper Abstract

The Surveillance Sciences Directorate of the Northrop Grumman Advanced Systems and Technology organization is developing a novel Multispectral IR camera known as Multiview. This prototype system is capable of simultaneously acquiring 4-color SWIR/MWIR 2D imagery that is both spatially and temporally registered utilizing a single 2562 HgCdTe snapshot IR FPA capable of frame rates in excess of 240 Hz. The patented design offers an extremely compact package that contains the entire optomechanical assembly (lenses, interchangeable filters, and cold shield) in less than a 3 in3 volume. The unique imagery collected with this camera has the potential to significantly improve the effectiveness of clutter suppression algorithms, multi-color target detection and target-background discrimination for a wide variety of mission scenarios. This paper describes the key aspects of the Multiview prototype camera design and operation. Multiview's ability to dynamically manage flux imbalances between the four subbands is discussed. Radiometric performance predictions are presented along with laboratory validation of many of these performance metrics. Several examples of field collected imagery is shown including examples of transient rocket plume data measured at 240 Hz sample rate. The importance and utility of spatio-temporal multi-band imagery is also discussed.
