A Shortwave Infrared Imaging System for Ultra-High-Speed Tracking of Multiple Targets

We will develop and deliver an imaging system capable of simultaneously tracking up to 8 independent objects at rates in excess of 1000 frames per second. The system will incorporate a novel indium gallium arsenide focal plane array and camera and will be sensitive to the 0.9 mm to 1.7 mm shortwave infrared wavelength band. The final deliverable will be capable of imaging multiple regions-of-interest ("windows") of random sizes, shapes, and locations and will allow for potentially overlapping windows. Algorithms will be developed for the identification of the relevant objects with tracking implemented by relocating the windows after each frame. In the final system, the tracking algorithms and implementation will be included in on-board system logic. The final imaging system will be compatible with Sensors Unlimited's MicroCamera architecture and thus suitable for use in missiles and unmanned aerial vehicles. During Phase I we will develop a proof-of-concept demonstration using focal plane arrays and cameras currently under development for other DoD programs as well as design of the control logic of the Phase II focal plane array. The Phase I final deliverable will consist of an imaging system including both hardware and software suitable for replicating the proof-of-concept demonstration.
