A rotating laser according to the invention has a source of electromagnetic radiation , in particular a laser beam source, for production of a reference beam, and deflection means, which can rotate about a rotation axis, for rotating transmission of the reference beam, by which means a laser area is defined, and with the reference beam passing over a reference path, and with at least a portion of the reference path being perceivable visually and/or by means of a detector on a surface as a reference line . Furthermore, swivelling means are provided for swivelling the rotation axis about at least one swivelling axis, in particular about two swivelling axes as well as a range measurement unit for measurement of ranges to points on the reference path, and control means for controlling the swivelling means and for comparison of ranges. Furthermore, the rotating laser has a functionality for perpendicular alignment of the laser area relative to the surface , with the control means being designed such that the laser area is automatically variably inclined relative to the surface by swivelling of the rotation axis, with a reference line range from the reference line to the rotating laser being determined for each of the respective inclination angles, and with that inclination angle of the laser area being determined as the perpendicular inclination angle at which the laser area includes the reference line with the respective shortest determined reference line range, and therefore being perpendicular to the surface . |
