Abstract
Device for vibrationally deviating an optical beam. It includes a frame, a main mechanical resonator, an auxiliary mechanical resonator and vibration generator means. The main mechanical resonator is formed of an optical member such as a mirror and resilient means connected to the optical member and the vibration generator means impress upon the optical member through the resilient means a rotational or translational motion, the frequency of which is that of the main resonator. The auxiliary resonator is formed of resilient blades having a free end and another end connected to the frame and its resonance frequency of the auxiliary resonator is equal to the resonance frequency of the main resonator. The two resonators vibrate in phase opposition in order that the periodic mechanical stresses applied respectively by the two resonators to the frame have at any instant, one and the same direction and opposite senses.
