Abstract
Image motion compensation (IMC) can be used to augment conventional line-of-sight (LOS) stabilization systems to improve stabilization performance. The tradeoffs involved in deciding when to use IMC and the expected performance improvements are reviewed. Several IMC concepts are outlined including the special case of a gimbaled optical element with a one-to-one scale factor between mechanical and image motion. The advantage of this IMC stabilization approach over other IMC techniques is that performance is not limited by the bandwidth of the sensor or actuator. Performance, however, is limited by optical scale factor accuracies. Precision measurement of the gimbal motion is not required to achieve LOS stabilization. The "restored mass stabilization" approach offers performance improvements without the high cost of precision inertial components.
