<p>The invention relates to a dual-laser-scanning optical device having multiple adjustable parameters and consisting of two continuously-rotating wedges, each rotating wedge comprising two counter-rotating prisms which are disposed consecutively on the path of the laser beam. According to the invention, the following parameters can be adjusted: a1, a2, a3, a4, i.e. the angles at the top of the prisms of the two wedges (25, 26); ?1, ?2, ?3, ?4, i.e. the speed of rotation of the prisms of the two wedges (25, 26); n1, n2, n3, n4, i.e. the indices of the prisms of the two wedges (25, 26); and ß1, ß2, i.e. the angles formed between the two prisms of each wedge (25, 26) in a plane that is perpendicular to the axis of the beam.</p> |
