【Abstract】 The Tracking system can measure the traveling distance with the laser working in infra-red wave band by measuring the phase difference with modulated light wave shuttling the measured distance. The real time measuring distance and the traveling speed of the traveling object can be realized without transmission error with DSP technique. The actual location of the traveling object can be clearly indicated and the traveling speed can be well controlled digitally.更多还原
