Abstract
Open-loop or feed-forward image stabilization systems and related techniques are provided to improve the accuracy and reliability of imaging systems. An open-loop or feed-forward image stabilization system includes a fast steering mirror assembly, an angular motion sensor, and a logic device. The fast steering mirror assembly adjusts a propagation direction of an optical path for an imaging system. The angular motion sensor is configured to measure and provide an angular motion of the imaging system. The logic device is configured to provide open-loop or feed-forward control for the fast steering mirror assembly by determining a compensating angular offset for the fast steering mirror assembly based, at least in part, on the received angular motion of the imaging system, and by controlling the fast steering mirror assembly to adjust the propagation direction of the optical path for the imaging system according to the determined compensating angular offset.
