The invention relates to a microscanning device for deviating periodically a convergent beam. The device according to the invention is comprised of an assembly (33) consisting of an even number of thin blades (21-28) which are opposite by pairs, and forming a regular polygon. The assembly has a symmetry axis ( DELTA ), arranged perpendicularly to the direction (Rm) of the convergent beam (FC), and is actuated with a uniform rotation motion about the axis ( DELTA ). The invention applies to the microscanning in one or two directions, according to the cross-sectional shape of the thin blades, for bidimensional sensors of infrared cameras.
