SURVEYING DEVICE COMPRISING A RANGE IMAGING SENSOR AND A SETTABLE TARGET ILLUMINATOR TO PROVIDE AN AREA ILLUMINATION IN DIFFERENT ILLUMINATION STATES

The invention relates to a surveying device (1) embodied as total positioning system or total station, wherein the surveying device (1) comprises a laser distance measuring module configured to generate a distance measuring beam for a single point measurement to determine a distance to a measurement point targeted by the distance measuring beam. Furthermore, the surveying device (1) comprises a range imaging module with a switchable target illuminator (10) for providing different distance-dependent illumination states (12, 14, 15) of an area illumination comprising a broad and a narrow illumination state.
