Abstract
A target object (20) for a laser measuring device (11) emitting a search beam and a measurement beam, including a reflector device (21) having at least one reflector element (22) for reflecting the measurement beam, a receiving device (23) having at least one receiving element (24) for receiving the search beam, a transmitting device (25) having at least one transmitting element (31, 32, 33) for emitting a visible transmission beam (34, 35, 36) and a control device (26) having an evaluation element (27) for evaluating the received search beam and a control element (28) for controlling the receiving and transmitting devices (23, 25) is provided. The transmitting device (25) emits a first and a second visible transmission beam (34, 35), wherein the color of light of the first visible transmission beam (34) differs from the color of light of the second visible transmission beam (35).
