<p>The invention in question relates to a laser arrangement (1). The device includes the means (2, 4) to steer the laser beam across a reflecting body (3). The body (3) is arranged to reflect the said laser beam so that it is aimed in a surrounding space within an area that, from an instrument plane (11) of the reflecting body (3), covers at least a part of a circular revolution, as well as an angle interval approximately ± 60° to the instrument plane. The device is characterised in that its steering means (2, 4) is arranged in the path of the laser beam between the laser (1) and the reflecting body (3), and is arranged to steer the laser beam, within the area, in accordance with a pre-selected direction, whereby the steering means comprises a spatial light modulator (2), whose phase-shift pattern determines the modulated angle from the modulator.</p> |
