A low cost high performance constant fraction discriminator (CFD) for
laser rangefinder using pulsed TOF (time of flight) is proposed with the accuracy and
measuring speed been improved. A distance measuring system has been established
and experimental evidence is presented to show the feasibility of solving the time
walking error problem to amend the precision and improving the environmental
applicability.
