A line of sight stabilization system using two mirrors pivotally mounted
to a fixed platform that can be used with existing imaging systems to
provide pitch, roll, and yaw compensation while maintaining image
orientation. By deflecting only the photons, the inventive system avoids
the need to stabilize the entire imaging sensor and optics system. The
only mass to move is that of the two imaging system mirrors. By
monitoring attitude changes via an inertial measurement system,
proceeding platform positions can be estimated for subsequent image
acquisitions, and efficient mirror positioning can provide optimal image
orientation and stabilization. This approach requires small motors with
low torque, providing a less expensive, lightweight, and small image
orientation and stabilization system.
