An enhanced optical delay line device for providing multiple degree of freedom active control, including first and second actively-controlled mirrors, each of the actively-controlled mirrors having two rotational degrees of freedom and one translational degree of freedom. The first actively-controlled mirror is mounted substantially orthogonally to the second actively-controlled mirror. The system also includes a closed-loop control system, the control system providing six mechanical degrees of freedom of active control for the enhanced optical delay line device by controlling the first and second actively-controlled mirrors based upon a command input and mirror position signals. The present invention is smaller than conventional optical delay line devices, has better performance, and eliminates the need for one of the FSMs, bringing the total number of mechanisms down to two from three.
