PURPOSE:To supply a route command and a speed command to a ground moving body, and to utilize a laser beam effectively, by rotating a laser beam reflector under the command of a CPU, and allowing the beam to pass through the reflector. CONSTITUTION:A reflector 32' is installed so that its rotating shaft is at distance (d) (l/2 d) from a beam LB. While the reflector is between points C and B, a reflcted laser beam scans on the ground surface between B'' and C'' and when the reflector is not in the section CB, the beam LB passes through the reflector 32', so the beam scans on the ground surface intermittently. Namely, an impulsive scanning beam is obtained. For the purpose, the number of rotation of the reflector 32' is controlled under the command of a separately provided CPU1 to send a speed command to a ground moving body at the repetitive frequency of the impulsive laser beam. A doppler phenomenon due to the speed of the moving body is corrected by a speed command detecting circuit. |
