ABSTRACT:
System for optically aiming a laser beam on to a target. The system comprises a mirror which reflects the laser beam towards the target and which is supported by a base by means of a pivot and first and second vibrating control members. This pivot and the control members together determine a first mirror rotation axis and a second mirror rotation axis perpendicular to the first axis. Means are provided for respectively generating a first and a second reference signals for driving the mirror. A laser radiation detector receives the laser radiation reflected by the target and produces a reception signal from which are derived first and second reaiming signal components. The first and second vibrating control members are operated by respectively the sum of the first reference signal and the first reaiming signal component and the sum of the second reference signal and the second reaiming signal component.
