Abstract

To meet the requirements of a variety of applications, range precision is an important specification for three-dimensional laser radar systems. The proposed laser ranging systems adopt electro-optical modulation and only measures the energy of a laser pulse to obtain range, so that it can reduce many errors in comparison to conventional systems. In this paper, the principle of continuous and pulsed laser ranging systems are introduced, through simulation analysis the target of 20 m, the continuous laser ranging system can achieve a range precision of several centimeters, and the pulsed laser ranging system can achieve a rang precision of several millimeters. And by analyze their advantages and disadvantages, it can be concluded that pulsed laser ranging accuracy is higher than the continuous laser ranging systems. The pulsed laser ranging system is expected to be an alternative method for three-dimensional laser radar system requiring high range precision in many applications.
