Paper Abstract

A new method for measuring absolute distance is described which is based on the frequency modulated continuous wave (FMCV technique. The preliminary experiment results show that the accuracy can reach 0. 3mx at a distance of 7 meters and the measuring range can exceed 10 meters by using an external cavity laser diode
