FIELD: optics.
SUBSTANCE: method and device for scanning target area (218). Deflection (230) of laser beam (216) used during scanning of target area (218) is specified. Laser beam (216) is directed to different sections (220) in target area (218) at scanning angle (226). Angle (226) of scanning laser beam (216) is set when laser beam (216) is directed to said different sections (220). Variation of divergence (230) and/or value of change of scanning angle (226) during scanning of target area (218) results in change of resolution (240) for target area (218).
EFFECT: disclosed is an active optical system with variable resolution.
