Real Time Adaptable ROIC for improved Power and Performance Optimization in Imager Systems

The primary objective is to provide the concepts and architecture for a real time adaptable ROIC that can be configured dynamically to meet the needs of the application and the real time conditions. Intrinsix will investigate the methods to sense the scene content and to dynamically adjust resolution, frame rate, dynamic range and/or sensitivity as needed to adapt to changing image quality requirements and power consumption needs. The architecture developed would apply to many mobile camera systems including visible, near-IR and short wave IR imaging systems. It will also present a common electrical and physical interface to the larger system. The ROIC design will be scalable in order be used with a variety of array sizes and a range in the pitch of the pixels. Identify Circuit topologies suitable to support programmability for lowering power when warranted by a particular usage mode. Work will build upon efficient topologies used on previous projects. Use Matlab and Simulink to model expected performance. This will be achieved by leveraging: Intrinsix"s experience with ROICs and A/D converters Significant R & D expenditures on the use of configurable SDMs. The serpentine SDM ROIC designed under AF SBIR 093-160
