Abstract
A laser scanner has a first axis and a second axis extending essentially transversely to the first axis. A measuring head is adapted to be rotated about the first axis. The measuring head has at least a first, a second, and a third module, wherein at least the first module and the third module are releasably connected to each other. A first rotary drive for rotating said measuring head is comprised within the first and the second modules. A rotary mirror is adapted to be rotated about the second axis. The rotary mirror is comprised within the third module. A second rotary drive is provided for rotating the rotary mirror. The second drive is likewise comprised within the third module. A transmitter is provided in the measuring head for transmitting a light beam. A receiver is provided in the measuring head for receiving the light beam after a reflection thereof by an object located at a distance from the laser scanner. A computer is provided in the measuring head for processing signals embedded within the received light beam.
