Abstract
The present invention concerns a laser scanning system (18) comprising: —a first acousto-optical deflector (30) deflecting a beam in a first direction (X) to obtain a first deflected beam and comprising a first acousto-optical crystal on which is applied an acoustic wave whose frequency varies over time according to a first law of command, and —a second acousto-optical deflector (32) deflected the first deflected beam in a second direction (Y), defining an angle comprised between 85° and 95° with the first direction, and comprising a second acousto-optical crystal on which is applied an acoustic wave whose frequency varies over time according to a second law of command, characterized in that the first law of command and the second law of command are chosen so that the average speed of the laser scanning system (18) is superior to 10 radians per second.
