<p>According to the invention, the imaging system contains an impulsion light source (1) for an input light beam (FI) oriented toward an observed area (ZO) and an optoelectronic sensor (3) having a photosensitive surface (31) with a visibility capable of substantially covering the observed area. An impulsion of the incident light beam is backscattered by only by a portion (PZO) of the observed area into a backscattered spot (TR) on the photosensitive surface (31). A deflection device (2) deflects the impulsions of the incident light beam onto the respective portions of the observed area. A device (4) acquires thumbnail images corresponding to the backscattered spots resulting in impulsions of the incident light beam. The system combines said thumbnail images to produce an image having a sufficiently high signal-to-noise ratio for portions of interest of the observed area, a high spatial resolution, and a greater insensitivity to motion blurs.</p> |
