Abstract :
The main application of laser range technology are phase technique and pulse technique. The paper based on the introduction of the basic theory of laser ranging. Mainly introduces the laser range technique of single modulation continuous-wave. By measuring the integer sine wave number and the phase difference of laser modulation signal on the way light and forth to confirm the target distance. This method not only guarantees the accuracy of measurement but also improves potential measure distance. The feasibility of single modulation continuous-wave laser range technology has been proved by programming and software simulation. The paper makes analysis of relationship between frequency and distance.
