This paper deals with a laser scanning device used in a space-encoding rangefinder. At first the principle of space- encoding is introduced. And then the error expressions of the rangefinder are given on the basis of establishing its mathematical model. Furthermore are deduced the functional relations between the measurement errors and parameters of the laser scanning device as well as errors of the parameters. At last approaches to reduce the measurement errors caused by the laser scanning device are found out according to the above said error expressions and functional relations.
