Abstract: This paper introduced a new laser range testing method which has high precision based on the Self-triggering Pulsed technology and the error model.The technologies of Self-triggering Pulsed,Constant Fraction Discriminator and the system error model,which were used for the high precision laser range finding,were presented in this paper.In the end,experiment result was presented,which was consistent with theories used in the laser range testing system.

Keywords: Laser arrange finding; Self-triggering pulsed; Time of flight; Constant fraction discriminator; High precision
