Abstract
In order to improve measurement precision,the principle of phase laser ranging system and the method of improving measurement precision are discussed.Frequency generating circuit,difference frequency of phase measuring and digital phase measuring circuit are analyzed.the principle of difference frequency of phase measuring is proved theoretically.And the influence of digital phase detecting on measurement precision is explained by an example.Finally,some specific methods are introduced to improve precision and stability of the system for improving frequency drift and,phase measurement.
