摘要
We proposed a method of Linear Frequency Modulated Continuous Laser (LFMCL) heterodyne for distance measurement which based on monostatic system, and. designed the distance measurement scheme and analyzesdis of the heterodyne measurement principle. We also analyzed the feasibility, measurement accuracy of this method by simulation and get the frequency difference of the heterodynes in the distance of 300 m, 600 m and 900 m. Then established the experiment system of distance measurement by delay optical fiber, get the experimental results of the fiber length. The measurement results showed that: the relative error of method of LFMCL distance measurement based on monostatic system was less than 0.1%. (c) 2015 Elsevier B.V. All rights reserved.
