ABSTRACT:
A method and a device for suspending and driving into oscillation a space telescope oscillating mirror connected to a support whereby angular motions of the oscillating mirror around an oscillation axis are controlled from an auxiliary mass which is adapted to oscillate around said oscillation axis, and potential energy is momentaneously stored, for example in elastic form, when said oscillating mirror and said auxiliary mass come close in opposed phase to respective extreme angular positions. These oscillating mirror and auxiliary mass are preferably connected to the common support through flexible rods bound to said support. Dynamic oscillations in the support are thus minimized so as to allow precise observation in two neighboring directions, particularly for celestial scanning.
