ABSTRACT:
The invention provides a scanning mirror system with line of sight stabilization. In one embodiment a mirror and a balance member are mounted to rotate and the mirror is coupled by means of gear teeth to the balance member so that the inertia of the balance member tends to compensate for the inertia of the mirror. The mirror is arranged to be rotated by a drive motor and a gyro, driven at twice the mirror angle, is arranged to detect rotational movement of the mirror. The gyro is connected in a feedback control system with the drive motor in order to tend to maintain the mirror stationary when the mirror is not being driven through a desired angle by the drive motor.
