Abstract

A new method of laser range finder for precise large scale metrology is proposed. A chirped laser pulse with femtosecond durations is selected to work as the laser resource for the pulsed lidar to obtain the distance information. The chirped pulse's time domain and frequency domain specification are fully used in the double modulation, which combines the time-of-flight methods' advantages in distance measurement, such as high resolution, large measuring range and without measuring reference. An opportunity of absolute large scale metrology with the high accuracy is shown.
