Abstract
An optoelectronic device for multidirectional capture of images, comprising a retro-collector, two independent deflectors and retro-collection means (11), whose deflection means comprise two extending along orthogonal axes and respective deflector drivers coupled to oscillate the deflectors at a specific amplitude between two positions about their axis. The optoelectronic device also includes a controller that controls the drivers so as to oscillate the deflectors at a relatively low frequency between two positions in a first mode, or at a relatively high frequency capable of stabilizing the deflectors between the two positions in a second mode.
