The invention concerns an optoelectronic multidirectional image acquisition device including independent means of deviation (18, 19) and retro-collection. The means of deviation include two mirrors (18, 19) extending according to orthogonal axes, each mounted on motor means (16, 17) capable of making them oscillate with a determined amplitude between two positions around their axis, and means of control adapted for supply of the said motor means, either with an adapted frequency to make the mirror (18, 19) oscillate between its two positions, or with a high frequency to stabilize the mirror (19, 18) between its two positions, by controlling in addition a continual variation in the cyclical supply ratio.
L'invention concerne un dispositif optoélectronique d'acquisition multidirectionnelle d'images comprenant des moyens de déviation (18, 19) et de rétro-collection (11) indépendants, et dont les moyens de déviation comprennent deux miroirs (18, 19) s'étendant selon des axes orthogonaux et montés chacun sur des moyens moteurs (16, 17) aptes à les faire osciller avec une amplitude déterminée entre deux positions autour de leur axe, et des moyens de commande adaptés pour permettre d'alimenter lesdits moyens moteurs soit avec une fréquence adaptée pour faire osciller le miroir (18, 19) entre ses deux positions, soit avec une fréquence élevée apte à stabiliser le miroir (19, 18) entre ses deux positions, en commandant de plus une variation continuelle du rapport cyclique d'alimentation.
