Abstract
Provided herein are various improvements to optical-inertial stabilization systems, such as those employed on electro-optical systems that receive or emit optical energy. In one example, a system includes an optical reference element rigidly coupled to a primary mirror. The optical reference element propagates a reference signal through optic elements that form at least a portion of an optical path corresponding to the primary mirror. A measurement of the reference signal is made after propagation through the optic elements to determine errors associated with the optical path. The system can also include inertial sensors rigidly coupled to the primary mirror and optical reference element to form an assembly. The inertial sensors are configured to measure inertial rotation of the assembly. Rotational adjustments about two axes can be produced for the assembly based at least on the inertial rotation properties to correct for disturbance or drift.
