a carriage 1 travels along a path (4) and by a flexible link (7), a frame 6 which is fixed to a load 2 of an optical element.a linear actuator for controlling the route 7, 8 so as to overcome the shortcomings of the displacement of the load 2.a piezo electric accelerometer 21 delivers a signal for controlling the linear actuator 22 through 8 so as to eliminate the effect of vibrations of the carriage 1 to the load 2.there are two independent control loops for the control of the trolley, on the one hand, and for the control of the chassis respectively.;application to the control of the movable part of an optical delay line 11, and a telescope, a stellar interferometer.
